Custom SMTP


Using Your Own Email Server

The primary reason for using your own email server is to ensure that your emails don't get blocked by spam filters and/or firewalls. Using your own email server also allows you to use your own email address for all of the LMS emails which can provide a more immersive experience for your learners.

If you do wish to have email messages from the LMS come from your organization's email domain (i.e., the message must be relayed and sent through your organization's own SMTP Server.

To implement custom SMTP settings within you portal, you will need to open a Support Ticket, and provide the following details:

  • Server: SMTP Server Address, e.g.
  • From Email Address: eg.
  • SMTP Security: You can choose between None, or TLS encryption
  • Port: The associated port on the server
  • Username: This is usually the same as the From Email Address, but may be different depending on your settings
  • Password

Our Support team will enable custom SMTP for you, as clients do not have access themselves, and will get back to you to confirm that the request has been completed.

Please note: Absorb does not support sending messages directly as a client's email domain through the LMS.

When sending large groups of emails from the custom SMTP service, it is important to know that it currently limits the amount of emails that can be sent both per minute and per day and once the limit is reached, the SMTP will reject further connections from absorb.  Therefore, very large groups of enrollments, user creation, or other email groups may experience dropped/missing emails even when sent from this custom SMTP.
