I'm using RHEL6 instead of ubuntu, but check the startup scripts. In
RHEL's case, the following file is sourced, so I updated it instead of
the startup scripts.
cat /etc/sysconfig/dovecot
# Here you can specify your dovecot command line options.
#
#OPTIONS=""
ulimit -n 4096
ulimit -u 5120
In addition, I had to also up the max allowed processes in the dovecot
config. 2.x and 1.x are different on this.

Thanks Frank.
Followed the URL and could not find any luck.
Is there a way to change the value of 'max open files' of dovecot.
I have tried to set the value in /etc/default/dovecot by setting
ulimit. But the value is not getting applied.
Could anyone help on this regard.
Fasil.

Dear all,
Thank you all for such a wonderful support. Hats off to all :)
Few times I came across imap login issues where new users will not
be allowed to login.
/var/log/mail.err shows the error below
Aug 12 07:57:46 mail dovecot: dovecot: pipe() failed: Too many open
files
Aug 12 07:57:46 mail dovecot: dovecot: Temporary failure in creating
login processes, slowing down for now

I have a dovecot (V 1.2.9) +postfix (V 2.7.0) setup on ubuntu 10.04
# ulimit -Hn
1024
# ulimit -Sn
1024
# cat /proc/sys/fs/file-max
1238548
# cat /proc/`pidof dovecot`/limits | grep 'Max open'
Max open files 1024 1024 files
Please advice how to get rid off this.
Fasil.
