Update: I had to fall back to the 1.2.17 dovecot code. Doing that
solved the invalid user settings and dovecot inability to auto detect
between mbox and Maildir format for user accounts and no longer have the
limited number of imap processes either.
Not sure what I was missing in the config files, but this is the route I
will stay on for now. If it helps here is the 1.2.17 config:
root@mail2:/userM/mail-services/dovecot2/sbin# ./dovecot -n
# 1.2.17: /userM/mail-services/dovecot2/etc/dovecot.conf
Warning: fd limit 256 is lower than what Dovecot can use under full load
(more than 3072). Either grow the limit or change
login_max_processes_count and max_mail_processes settings

That didn't work. Still seem to stop accepting new imap connections when
we hit around 500 processes.

Hi,
not shure if that helps.
In 10-master.conf file exists a "service imap { ... }" section.
You could try to increase the "process_limit = " parameter in it.
On one of oour servers there we have "process_limit = 2048" and we habe
about 1200 concurrent connections without problems.
Best,
Urban

It's not fixed. Now the limit looks to be around 500 processes and we
start to get number of connections exceeded. Any ideas?

I fixed this issue about the process limit in the 10-master.conf file:

It looks like on the system that once we hit around 200 imap processes
it stops there and no more imap processes can be created. Is there a
number of max imap processes in the config file somewhere. By the way

Another problem is people are getting error message from their

well, how much folders do the have
keep in mind that fpr IDLE you have one connection per user and
folder
10 users with 10 folders behind the same NAT router are 100
connections
from the same IP

All,
Just move our mail servers over to a new mail server running
postfix
2.11.1 and dovecot 2.2.13 and getting the subject line errors
in my
/var/adm/files. People are complaining of loosing their
connections to
the mail server.
I've been able to google this error but haven't found fix for
this
yet.
NOt sure where to put the drop-priv option in the config files
either.
Any suggestions?
