SMTP / POP3 settings upgraded to support SSL encryption

As continuation of our security hardening practices, we will be officially ending the ability to use plaintext authentication for email services. This change should impact less then 1% of our customer base still utilizing these legacy features. It is recommended to review the following changes to ensure your services will not be impacted.

A detailed breakdown of the changes is as follows:

Incoming e-mail 

  • Plaintext authentication for POP3 and IMAP will be disabled. 
  • Connections to the servers on ports 110 and 143 will not be allowed. 

Outgoing e-mail 

  • E-mail clients will be required to connect with SSL/TLS before being allowed to authenticate.

As a result, please review your mail clients for the following settings, adjusting as required:

Incoming Server:
IMAP Port: 993 or POP3 Port: 995 
Outgoing Server:
SMTP Port: 465 
SMTP Authentication = On
SSL: Enabled

NOTE: Authentication is required for IMAP, POP3, and SMTP.
These changes will take effect on: September 8, 2017 from 2:00 A.M -- 3:00 A.M EST.
