I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below
550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message
We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards.
Does anyone understand how the CPanel config works?
don't use crap like POP-before-SMTP in 2014
that don't really work in times of carrier grade NAT and mobile devices where thousands of complete independent users coming from the same gateway IP
use SMTP auth
