In December, Rackspace are removing nonencryped access for IMAP, POP, and SMTP. Insecure access sends the username and password in plain text over the network. Bad actors can exploit this vulnerability to steal the username and password for the mailbox. Secure access encrypts the data, protecting against main-in-the-middle attacks, attackers reading a message in transit, and messages being forwarded to attackers.
To prepare for this change, you'll need to reconfigure any clients connecting insecurely. The secure settings are:
- Secure IMAP: secure.emailsrvr.com (Port 993)
- Secure POP: secure.emailsrvr.com (Port 995)
- Secure SMTP: secure.emailsrvr.com (Ports 465 or 587)
- Be sure to select options for secure TLS.
To avoid disruption please make sure now that you're using the new secure settings.
Thank you for your prompt attention to this matter.
