You could try increasing vsz_limit to something like 512 MB. Do you
have mailboxes with a large quantity of emails (as in thousands) that
256 MB isn't enough?
Mike
I felt like that was a clue, but have no idea how to set vsz_limit,
however there is no mail on the system. I got those errors just testing
imap login from mutt.
Have a look through the config files in /etc/dovecot/conf.d
Mike
Yeah I found it hiding out in 10-master.conf upped it to 512MB as
suggested with no luck. Then just for fun I upped it to 5000M and still
no luck.
Edgar
I just noticed in the log even after raising vsz_limit the error remains
the same claiming vsz_limit=256MB
This is a know bug. If an unknown user tries to log in, the login code
goes into a loop expanding a buffer until it runs out of mem. The
cause of the bug is also known, but nobody (including myself) came up
with a diff yet.
The login process gets rsstarted, so there is no immediate functional
problem, apart from the log being filled.

Thanks for all the replies. Not sure what I was doing wrong I was
trying to use bsdauth, but could never get it to let me login. Switched
to MySql and its working. No more memory errors in the log.
Of course there are no more memory errors when you changed the
authentication mechanism. Otto mentioned to you the reason for the
errors.
