Interesting. In the 2.3.20 tag, I found the code that prints that message in src/login-common/client-common.c ... but that same code is not present in the main branch. It looks to me like that code has been completely overhauled and maybe 2.4 won't have this problem when it gets released.
Hmm. Maybe I am wrong. I grepped my log for inactivity disconnects that do not say "auth failed". All of the things it found were for my email address, and had a timeout of 1800 seconds, not 180 seconds like the ones for the other user that say "auth failed."

So maybe the other user with the auth failed messages was actually failing auth. Today they actually got banned by fail2ban because they had a ton of the "auth failed" logs in quick succession. I re-iterated the correct IMAP server settings and there hasn't been a repeat of that log message since that time. Maybe they had actually typed in the password wrong.
Apologies for the noise! Thanks, Shawn _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
