Basic and Premium/Secure High Volume

LuxSci's High Volume Email Sending Service includes two service options, "Basic" and Premium. Basic High Volume is a stand-alone SMTP-only service that is available by special order only for customer with large-scale SMTP relaying needs.

"Premium" High Volume (also known as "High Volume Secure Sending" is an add-on to Business Email Hosting which provides full featured secure email sending with high sending limits. Both options have the same set of capabilities and reporting options that you need to send your emails and to track their status. The Premium High Volume service provides more extensive security options, such as HIPAA compliance, outbound email encryption, email archival, and additional administrative features and controls.

Dedicated Servers

Dedicated servers are used for all Basic High Volume customers and are available for to Premium High Volume customers we all. Dedicated servers are ideal for IP reputation management and consistent sending throughput.

Feature Basic Premium
Dedicated IP Address
SLA (Service Level Agreement) includes 100% network and infrastructure guarantee
Separation from other customers ensures you aren't affected by
their usage patterns or reputation
Branded Email Headers [Optional]

Dedicated server customers can choose to have the headers of all outbound messages "branded" with their domain name and organization and with all references to LuxSci and "High Volume" removed:

  • Hostname: the server hostname that appears in the mail headers will be your server name (e.g.. "" instead of ours (e.g. "")
  • Reverse DNS: Anyone looking up the hostname of your server from its IP address will get your custom hostname back, and not a LuxSci server name.
  • Abuse Email: Include your own "Abuse Reporting" email address in the headers instead of ours (though the emails will still be routed to us).
  • Powered by: Include your own "Powered by" header line in place of our "LuxSci High Volume" header line.


LuxSci's High Volume Email Service provides a robust set of features to maximize prompt delivery of your emails.

Feature Basic Premium
Use Your Own From Addresses

You can only send messages from an email address in a domain that you own. Addresses from "free email services (e.g., hotmail)" are prohibited.

  • Basic Service users can send from multiple "from addresses" or domains that have been approved by LuxSci Support.
  • Premium Service users can send from any email address in a domain that they own or manage, the approval step is not required.
Reverse DNS (rDNS) records
Reverse DNS records point the IP address of your email server to the server's domain name. This information reduces the risk of the receiving server viewing the email as spam.
Alternate SMTP Ports
Alternate ports for SMTP access: 80, 465, 587, 2025, 6025, and 6465. If firewalls or ISPs attempt to block your messages, sending your email via these alternate ports helps ensure that your messages are delivered.
DKIM - Sign outbound messages
DKIM allows receiving email servers to feel more confident that the email originated from the listed domain, increasing the deliverability of your message.
SPF and Sender ID authentication information is used by receiving email servers that are checking for spam. The existence of this information reduces the chance that your email is blocked.
Anonymous SMTP - IP Masking
Anonymous SMTP hides the IP address of the computer or server that is sending the message. This feature increases deliverability when you are sending from an ISP or location that is blocked or has a poor reputation.
IP Monitoring
LuxSci checks its server IP addresses to make sure that they are not on blacklist databases and to immediately alert us of any blacklisting issues so that they can be immediately addressed.
Graylist and blacklist resolution
LuxSci works to resolve problems that may have resulted in your IP being gray or blacklisted.


LuxSci's reports enable you to detect delivery successes, failures, and SPAM complaints so that you can easily manage your mailing list and resolve unexpected problems.

Feature Basic Premium
Messages Sent
This online or emailed report lists successfully sent messages. It can be downloaded, sorted, and searched
Tracking and Deliverability
This online or emailed report lists the delivery status of every message sent to every recipient. It can be downloaded, sorted, and searched. For messages that were not successfully delivered, the delivery issue is listed. Summary reports are available on a daily and monthly basis.
Tracking Soft and Hard Bounces
Automatic tracking of delivery success and failure. Automatic processing of post-delivery bounce messages and updating of message delivery status. Automatic differentiation between "soft" and "hard" failure messages.
Email Delivery Status Digests
This emailed report lists all email delivery status updates for all messages sent to a specified email address or list. It is useful for automating processes and for automatically informing you of issues. It is delivered to you automatically on a frequency that you select (e.g., weekly). The report is sent to your email in HTML and also includes an Excel file for easy analysis.
Email Delivery Failure Reports
This report lists all email delivery failures and includes the reason why the delivery failed. The report is sent to your email in HTML and also includes an Excel file for easy analysis. It can be used, for example, to discover misspelled addresses and to remove non-working addresses.
Feedback Loops (SPAM notifications) with Major ISPs
LuxSci works with major ISPs to quickly detect spamming and other issues and to help keep our servers off black lists. LuxSci users can see SPAM complaints by logging into the system. Users can also have their SPAM complaints automatically sent to their email. Complaining recipients can then be easily removed from their mailing lists.
Auto-block future email to complainers (optional)
For recipients that complain that your messages are unwanted/spam-like, and where those complaints come back through the standard feedback looks from Major ISPs, LuxSci can automatically add the problem recipient email addresses to your domain-wide recipient block list. Thence forward, all email sent to those same addresses by anyone in the same domain will be automatically blocked (and logged).

Its your job to make sure that your mailing lists are opt-in and clean and to remove the addresses of everyone who complains in any way. Auto-blocking of complainers is a safety net for you -- even if you make a mistake and send to a complainer ... we will be sure the message is stopped before it gets to them.

This feature must be enabled in your domain's outbound email settings page.
