Outage Expected: 10-15 minutes.
Reason: Software Changes
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:
– Plaintext authentication for POP3 and IMAP will be disabled.
– Connections to the servers on ports 110 and 143 will not be allowed.
– E-mail clients will be required to connect with SSL or issue the STARTTLS command before being allowed to authenticate.
As a result, please review your mail clients for the following settings, adjusting as required:
Incoming Server: chi-rs36.websitehostserver.net
IMAP Port: 993 or POP3 Port: 995
Outgoing Server: chi-rs36.websitehostserver.net
SMTP Port: 465
NOTE: Authentication is required for IMAP, POP3, and SMTP.
