What protocol are you using? We use imap via TLS and we see this all the time in our logs, but it's actually working fine (first Exchange 2007, now 2010). I think it has unsupported auth mechanisms in its list, so we see these as it tries them, then fails to the next one.
Fetchmail has a non-daemon run mode that can give you a lot of info (fetchmail --vvv --nodetach --nosyslog -f /path/to/fetchmail-config-file) Brent Wiese From: [email protected] [mailto:[email protected]] On Behalf Of Cena, Stephen (ext. 300) Sent: Wednesday, May 29, 2013 11:04 AM To: [email protected] Subject: [rt-users] Fetchmail & Exchange 2003 have stopped playing nicely Now my fetchmail services on both servers no longer work. I keep getting authentication errors: http://www.fetchmail.info/fetchmail-FAQ.html#R15 Nothing I'm trying seems to work correctly. I'm guessing it's security patches on our Exchange server because this was working fine on our first server for over a year. I'm Google-ing RT and Exchange and not coming up with anything. Does anyone have any suggestions or links? Thanks!
