Learn about LuxSci WebMail

Watch a brief tour of LuxSci WebMail

Perhaps you were wondering...?

We include technical support with all accounts. LuxSci's support staff are located in the USA and are all US citizens. Standard support hours are 9am to 11pm Eastern Time, USA. During this time, our staff is standing by to answer your questions via email, support ticket, and phone. Emergency, mission-critical support is available 24/7/365. (Read more about LuxSci Support.)

In addition to SecureLine for email encryption, LuxSci provides a range of security features including two-factor login, password expiration, opportunistic TLS for inbound and outbound email, email header scrubbing, login auditing, custom firewalls, customizable session timeouts, and more. (Read more about the LuxSci security and privacy focus.)

LuxSci email works with any email program on any computer or mobile device, including Outlook, Mac Mail, Thunderbird, and the default email programs in iOS and Android. LuxSci email and SecureLine email encryption work through secure IMAP, SMTP, and POP connections from your programs to the server. There is never any need to download special programs, apps, or plugins. Additionally, LuxSci provides an option for using ActiveSync for real-time synchronization of email, contacts, calendars and more with your mobile devices and recent versions of Outlook/Windows Mail.

LuxSci includes 7x daily on-site and 4x weekly off-site backups of all of your email, Web, and other data. You can request free restores as needed, although very frequent or very complex restore requests may incur a surcharge. (Read more about backups at LuxSci.)

Daily and weekly snapshots also protect your sensitive data against server failure, and we can always restore all your data. (Read more on LuxSci infrastructure and reliability.

LuxSci also offers Email Archival for saving copies of all inbound and outbound email. These copies cannot be edited or deleted by anyone. We save them for up to 10 years.

A shared business-class email hosting account comes with 50GB of disk space that you share among all your users (we do not limit space on a per-user basis although you can opt to impose such limits). If you exceed your limit or want to buy more space, we charge $0.75/GB. (Read more at Business-class vs Enterprise Class and Standard Shared Hosting: Disk space limits.)

Dedicated server customers can get from 10 GB up to 9000 GB of space per server. Dedicated is the way to go if you have large-scale storage needs.

LuxSci permits you to send and receive email messages that are up to 200 MB each (for customers with Email Archival, the limit is 50MB/message).

Email hosting customers can send up to 300 email messages/day; customers can send each message to up to 1000 recipients. These messages are not for use with bulk emailing of any kind (See our acceptable use policy).

For email marketing and large-scale sending needs, we offer a separate High Volume service. We can add this additional service (and the associated cost) to your business email hosting account.

There's no explicit limit on the number of messages you can receive. However, the receipt of large quantities of messages all at once (many 100s or 1000s of messages at a time, for example) can cause your inbound email to suspend automatically to protect our servers from inbound email abuse and "mail bombs." If you need to receive large numbers of messages in a short time, LuxSci provides dedicated inbound email processing servers.

There are no limits on the number of users who can be in your account or the number of addresses you can have in your address book.

We don't limit the number of messages you can store in your email folder. It's important to note, however, that larger folders are slower to use than smaller folders (more than 100,000 messages would be extremely slow) and no email folder can contain more than 1 million messages.

The majority of our servers are located in the state of Texas, USA. Customers ordering dedicated servers can request that their servers be in other areas of the USA, London, Sydney, or Hong Kong.

LuxSci has an automated email migration service for transferring the email folders for all your users. (For more details, see Migrate Your Data to LuxSci.)

Compatible with All Major Email Programs

LuxSci supports many versions of all popular email clients (though we recommend using the latest version of each product if possible), both licensed and shareware.

Mobile Access (iPhone, Android, iPad, Blackberry, etc.)

Blackberries, iPhones, iPod Touches, iPads, Androids, Windows Mobile, and Palm WebOS are some of the more popular mobile devices available to professionals. LuxSci supports all of these phones, as well as any other phone or PDA that properly supports the IMAP, POP and SMTP protocols. If your phone doesn't support these protocols but does have a mobile web browser, you have the option to access your email using LuxSci's Mobile Site or login to our standard portal using our "Narrow Mode Interface".

Mobile Push Email

LuxSci's Premium Mobile Sync service includes "Push Email" for email viewing, real-time pushing of new email to your device, as well as for sending of outbound email from your device through LuxSci's servers.

Push email is good for mobile battery longevity and for getting notifications of new email messages as fast as possible.

IMAP with secure access over SSL and TLS
SMTP with secure sending over SSL and TLS
Anonymous SMTP (hide your IP)

Mobile Version of WebMail
Enlarge picture

LuxSci provides a standard, full-featured, Web 2.0 WebMail interface (a.k.a the "Full Site"). For the sake of usability and feature richness, this full-featured portal makes extensive use of graphics, cookies, JavaScript, HTML5 and some features of modern web browsers to enhance the user experience. It is also designed for a wide screen viewing area.

The software requirements that make the full-featured portal good-looking and easy to use also have their down sides. The "Mobile Site" is the solution to these concerns:

Access the Mobile Site automatically with a mobile browser by visiting:

  • Blazing Speed: If you have a slow Internet connection or limited bandwidth, the Mobile Site offers faster service. It has been optimized to use less bandwidth, which makes the pages smaller in size, faster to download, and easier to read on your mobile device.
  • Mobile Devices and Narrow Screens: The Mobile Site will work with almost any mobile device, tablet, or PDA that has a web browser. We work tirelessly to ensure the quality of Mobile site pages, especially on smaller screens.
WebMail with secure access over TLS
WebMail via optional easy one touch/click password-less logins
Private Labeled Branded WebMail
Email Folder Management Tools

We provide you with online tools for creating, deleting, renaming, managing, and searching your email folders.

  • Supports any number of folders
  • Folders can contain messages and/or other folders
  • Folders are accessible via WebMail and IMAP
  • Remove Duplicates: Configure removal of duplicate messages in any folder based on message ID, subject, sender address and size. Message removal can run automatically on a nightly basis or manually at any time at the push of a button.
  • Auto-deletion: Configuration options allow you to automatically remove "old" messages in any folder to: 1. Reduce the folder size to some fixed maximum 2. Reduce the number of messages in the folder to some fixed maximum 3. Eliminate messages older than a specified number of days.
  • Auto-Archival: Archival options can be designed to your specific needs. The function can occur as you prefer; daily, weekly, monthly, bi-monthly, yearly or when YOU feel the folder has exceeded desired storage size of message allotment. You can even have a folder auto-archived; which will move messages to a new dated subfolder at your convenience.
  • Offline Storage: Download your email folders as ZIP-compressed archive in UNIX- or EML-format for offline storage.
  • Create, rename, move, and delete folders and directories.
  • Concurrent Access: Makes it easy to share access to email by allowing multiple users, using different email clients, access to the same email folders concurrently without issue.
Email Folder Sharing
Email Message Tagging & Adding Keywords
Automated Suggestions from your Address Books

When composing email messages, WebMail will automatically give you recipient suggestions by searching all of your address books for matches; in the name, company, email and nickname fields. You can alter, eliminate or add to these suggestions via keyboard or mouse. This WebMail feature makes it quick and easy to enter recipient email addresses and avoid making errors.

Annotating Email Messages
Signatures: Custom Reply-To/From

WebMail signatures allow you to add personality to your email. In addition to adding a signature to the end of your messages, you can customize the sending name and address. This is ideal if you have many different email addresses [not all of which are hosted at LuxSci] and need to send email (from a single WebMail application) that appears to come from any one of them.

  • Unique signature technology; similar to other services' "personalities".
  • Support for unlimited signatures.
  • Each signature has independent HTML and plain text versions.
  • HTML signatures support embedded images
  • With Signatures you can include files that will attach to all messages sent using those signatures (e.g. add a vCard or a PDF with all messages).
  • Determine whom your email appears to be from (you specify the From address and name; From name can be in any language).
  • Determine to whom replies to your email will be sent (you specify the Reply-to address).
  • If you reply to an email, WebMail will try to match the recipient address of the email to one of your signatures so that you automatically use the right signature for the right email -- no mistakes.
  • Change your signature "on the fly" in WebMail and have the signature content automatically updated in the message.
  • Use signatures either at the top of or at the bottom of replies and forwards.

Use of signatures to send emails forged with addresses that you do not have permission to use is a violation of our Acceptable Use Policy.

International Locale and Language Support

LuxSci's WebMail interface fully supports sending and receiving email messages in any language or multiple languages:

  • View messages encoded in any language or languages.
  • Compose messages in any language or languages.
  • Configure default encodings to use when none are specified.

Outbound Email

Reporting: Messages Sent
Searchable, sortable, and downloadable reports of messages sent.
Reporting: Tracking and Deliverability
Searchable, sortable, and downloadable reports of the state of delivery of every message to every recipient. You can see what has been sent, what is still queued, what has been delivered successfully, what has failed ... and exactly why. Reports include the reasons messages may be delayed, exactly why they bounced, and what the recipient servers said when they were delivered. Aggregate reports give you overall delivery statistics on a daily and monthly basis.
SMTP Relaying with security access over TLS and SSL

LuxSci provides SMTP Relaying so that you can send email from email programs (WebMail does not require "SMTP" service to send email).

  • Secure SMTP via TLS and SSL, plus insecure SMTP
  • Alternate Ports for secure and insecure SMTP -- including port 80 -- which is open in most firewalls.
  • All of our email servers support TLS and will talk securely with other servers whenever possible (opportunistic TLS).
  • Anonymous SMTP: Remove all information about your sending computer (its IP address) and email client when sending messages. This feature is available over SSL and TLS as well for email security. It is available to all clients who subscribe to SMTP services. More about Anonymous SMTP
  • More about SMTP
DKIM - Sign outbound messages
[Optional] Configure DKIM for the domains from which you are sending and get information to add to their DNS so that your recipients can verify your messages and improve their deliverability.
Large Email Messages: up to 200 MB
Security: End-to-End Email Encryption (via SecureLine)
Anonymous Email (Hide your IP)
Bulk Outbound Email (High Volume)
Outbound Email Forwarding

Users can:

  • Send copies of all outbound email to a designated email address
  • Send copies of all outbound email messages to a server-side sent email folder (without IMAP)

Domain administrators can:

  • Send copies of all outbound emails, from all users, to a designated email address. Certain users can be exempted from this process.

Global taglines or disclaimers in text and/or HTML cab be configured to appear at the end of all messages sent by your users.

  • Applies to messages sent via WebMail and from email programs using SMTP.
  • Configurable on a per-domain basis
  • Taglines/disclaimers can be added as attachments or added as part of the message content itself.
Outbound Email Content Monitoring

Monitor the content of all messages sent from WebMail or from email programs using SMTP.

  • Search for keywords or key phrases
  • Use regular expressions
  • Searches all HTML and plain text message parts
  • Search your choice of the message subject, message body content, or both
  • Can block messages, send copies of matching messages to an auditor email address, or auto-encrypt matching messages
Smart hosting

LuxSci's authenticated SMTP services can be used as a "smart host", which allows users to relay all email from your internal server though our servers for processing before being sent out into the Internet.

With smart hosting, you can take advantage of all of LuxSci's SMTP features, such as automatic outbound email encryption, anonymization, taglines and content monitoring.

Our "Intelligent" Smart host feature treats your email as if it were sent by your individual users. It looks at the "From" address on each message, rather than the single user connecting to LuxSci's SMTP services. This permits enforcement of per-user SMTP limits, per-user reporting on SMTP usage, per-user customization of taglines, per-user exemptions from some tools, and full support SecureLine automatic end-to-end outbound email encryption.

Intelligent smarthost is included with our standard SMTP service.

Email Auto-Responders / Vacation Notices

Email auto-responders let you setup pre-defined responses to email messages that you receive while you are away -- out of the office, on vacation, or otherwise unavailable. They also allow for the configuration of complex automated response rules.

Features include:

  • Automatic response to incoming email messages.
  • Different responses based on to which of your email addresses or domains the message is addressed
  • Configure responses based on arbitrary criteria such as: sender address, subject content, body content, email header content, etc.

  • Customer-accessible audit trails of all responses sent. Includes when, to whom, for what responder, and what the subject of the original message was.
Email Forwarding and Email Aliases

An email alias is not an actual user, but rather a rule that indicates to whom the email should be delivered. Individual users can also configure email forwarding for their inbound email.

Features include:

  • Catch-all aliases to capture email to non-existent address at your domain.
  • Redirect email to any address at your domain to one or multiple real local or remote email address(es).

Auto-Download POP Email from Other Accounts

If you have other email accounts with POP access, you can download messages from these remote accounts to your LuxSci email folders.

Features Include:

  • Store information for an unlimited number of remote POP email accounts
  • Download mail from each account to any email folder
  • Have your email downloaded automatically every 20 minutes
  • Use your inbound email, anti-Spam, and anti-Virus filters, including Premium Email Filtering to filter downloaded messages before forwarding to your LuxSci account. This is a great solution when your remote email account doesn't permit email forwarding but you want to download and filter those messages.
  • Delete or leave the remote email on the remote server when downloading manually. Messages are deleted from the server with automatic message downloads.
  • Optionally preview messages before downloading: select what to download or delete.
  • Download email from one or ALL remote accounts individually or at once.
  • Secure POP (SSL) connections to remote POP servers.
  • Use "Signatures" to manage multiple email accounts.

  • When the message was sent
  • Who sent it and from what address
  • What the subject was
  • The address of the recipient that failed
  • Exactly why the delivery failed

These email alerts are HTML for easy reading and include a CSV (Excel) file with all of the data for easy analysis. With these reports you can always be aware of failed deliveries and do not have to worry about getting and reading bounce messages. You can configure these reports so that managers can get copies of the failure reports for users and thus can ensure that important messages are all properly delivered.

Feedback Loops with Major ISPs
We collect spam complaint reports via agreements with major ISPs to detect spamming and other issues quickly and to help keep our servers off of black lists. Users and administrators can see reports of SPAM complaints in our web interface. Users and administrators can also have digests of their received SPAM complaints automatically emailed to them (with detailed information in attached CSV files) so that they are made aware of issues as soon as possible and to make opting complaining recipients out of mailing lists quick and easy.
