Email Smart Hosting

Smart hosting connects your existing email service to LuxSci's outbound email servers. All outbound email sent by your users passes though LuxSci for processing before reaching your recipients.

There are many reasons why you would want Smart Hosting. For example, if you have an in-house Exchange server, Office365, or GSuite, you can use smart hosting to add encryption to you outbound email, mask your IP address, improve your email deliverability, add outbound email archival, etc.

Talk to an Expert

You need smart hosting if:

  • You use Office365 or GSuite and need outbound email encryption, processing, or better sending IP reputation
  • Your ISP will not allow your mail server to send outbound email, or limits the quantity of email that can be sent.
  • Your Exchange Server cannot send email directly for your organization.
  • Your outbound email systems do not support SMTP Authentication.
  • Your IP address(es) have a poor reputation, resulting in your outbound email being considered spam-like by recipients (Are Cloud Servers Bad for Sending Email?)
  • You need to hide the IP address of your mail server using IP address masking.
  • You must ensure all outbound email is Archived, or secured for HIPAA compliance.
  • ...the reasons go on and on.

GSuite and Office365 Smart Hosting

It is a snap to configure your Google Suite or Office365 account to send all outbound email through LuxSci for processing and delivery. All you need is a LuxSci email account that has users corresponding to all of your Google or Office users. E.g., if you have 100 users in the domain "" in GSuite, then you would get a LuxSci account for "" and setup the same 100 users. Once smart hosting is enabled in Office365 or Google, and smart host relaying is enabled in LuxSci for your users, all of your outbound email will seamlessly flow through LuxSci—no per-user configuration or changes are needed.

With GSuite and Office365 smart hosting, LuxSci users are authenticated by the Google or Microsoft IP addresses from which the messages are sent and are identified by the "From" address in the email messages.

Exchange, postfix, and sendmail smart hosting

If you are not using GSuite or Office365, then smart hosting works by:

  • Identify one of your LuxSci users as a "smart hosting" user
  • Configure exchange, postfix, sendmail, or whatever email system you use to smart host email by authenticating to LuxSci as this user (i.e. using its username and password).
  • LuxSci then identifies the actual sending user by the "From" address of the message sent.

Alternately, if your sending program does not support SMTP authentication and you have a dedicated solution, you can use our Custom smart hosting service:

  • You configure the IP address(es) of your sending servers
  • You specify what sending user(s) are associated with what IPs
  • Connections from these IPs are allowed and treated as if the specified users had actually authenticated.

Large Scale Email Sending

Smart hosting users have the same sending limits as other LuxSci business email users — 300 messages/day/user. If a user hits the 300 mark, his sending is suspended until the next day.

Some customers require higher sending limits. This is available for any smart hosting customer using our High Volume Secure Sending add-on. High Volume allows you to pick and pay for the sending volume appropriate for your account as a whole (in terms of a maximum number of message recipients each month). Customers requiring more than 100,000 recipients/month are required to get a dedicated outbound email server and IP address.

Smart Hosting Features

Reporting: Messages Sent
Searchable, sortable, and downloadable reports of messages sent.
Reporting: Tracking and Deliverability
Searchable, sortable and downloadable reports with delivery details of every message to every recipient. You see what has been sent, what is still queued and what has been delivered successfully. If a message was not delivered successfully, you will know exactly why. Reports include:
  • The cause of any delay
  • Reason why a message bounced
  • The recipient server's delivery response.
  • Aggregate reports give you overall delivery statistics on a daily and monthly basis.
    Reporting: Email Delivery Failure Reports
    Tailor and receive automated email alerts (for delivery failures) when and how you choose.
    • At a frequency of your choice
    • For any email address or list of your choice
    Alert details include:
    • 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. They also include a CSV (Excel) file with all of the data for easy analysis. These reports make it easy for you to manage your mailing lists, discover addresses that are spelled wrong, and to remove old and non-working addresses.

    Authentication by username and password
    SMTP Services authenticated with a username and password are supported and recommended.
    Authentication by IP
    SMTP Services authenticated by the connecting IP address and/or the From address in the message are supported for compatibility with systems that do not support username/password authentication (e.g. G Suite and Office365).
    SSL/TLS Security
    Use of your choice of insecure SMTP, SMTP over TLS, and SMTP over SSL. You may optionally choose to lock down your account to enforce the use of SSL or TLS.
    Alternate SMTP Ports
    Alternate ports for SMTP access, including use of port 80. This helps ensure the sending process even if firewalls or ISP blocking policies exist.
    IP Address Masking - Hide Your IP
    Hide the IP address of all computers or servers you use to send messages. Blocking your own address helps prevent messages from being blocked by the recipient.
    Message Size Limit
    200 MB
    Messages can be up to 200 MB in encoded size. This includes all attachments.
    1000 Recipient per Message Limit
    Sent to just one IP address or as many as 1000 recipients per message.
    Sending Limit: Users can send up to 300 messages/day
    (without High Volume)
    Individual users are restricted to 300 messages per day unless you sign up for a "High Volume" account, which allows you to send as many messages as you purchase.
    Sending Limit: Send to many recipients per month as you purchase
    (with High Volume)
    Feedback Loops with Major ISPs
    We collect spam reports via agreements with major ISPs. This helps us detect spamming and other issues quickly which helps keep our servers off of black lists. Users and administrators can peruse SPAM complains reports in our web interface. Users and administrators can also have digests of their received SPAM complaints emailed to them automatically. These contain detailed information in attached CSV files so users know about any issues as soon as possible, making opting complaining recipients out of mailing lists quick and easy.
    DKIM - Sign outbound messages
    [Optional] Configure DKIM for the domains from which you send and receive information. This allows the recipient address to add you to their DNS. This helps them verify your messages and improves deliverability.
    VERP - Variable Envelope Return Path
    [Optional] Automatic Return Path customization so bounced messages directly indicate failed addresses.
    Dedicated Servers
    Available for extremely high volume delivery to isolate your sending.
    Email Capturing
    Direct copies of all sent messages sent to another email address of your choice.
    Support for Email Archival
