I've already tried creating etc/default/dovecot chmod +x it and inside put ulimit but didn't work.

Also i've tried to put the ulimit into the /etc/init.d/dovecot linked file but i found still 1024 the limit kn dovecot. El 27/03/2015 22:03, Timo Sirainen <tss@iki.fi> escribió:

Hello guys we have Dovecot 2.0.19 and we are getting those errors opening files of dovecot Too many open files, we¹ve tried to increase limits in /etc/security/limits

/etc/security/ settings don't affect Dovecot (or any other server program). You need to put the ulimit commands somewhere in the init script. Or perhaps adding the ulimit command to /etc/default/dovecot would work. I don't know what's the correct Ubuntu way to do it.
