It's unclear what this has to do with Evolution, as you only mention a
cpanel mailer in your report.

Furthermore, IMAP has nothing to do with sending mail, only with
receiving it. Mail is sent using SMTP.

The problem would appear to be with your mail provider(s) or possibly
with the cpanel system, but it's hard to know without further tests.
I'd suggest trying a different mailer (Evo or Thunderbird for example)
to see what happens.
