dovecot - increase login_max_processes_count

Hi, failed to send an email with smtp block error.

check of the logs showed the account had these errors

Code:

server dovecot: dovecot: All login processes are in use. You may need to increase login_max_processes_count

Code:

server dovecot: IMAP([email protected]): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances

I have done a google and seems i need to edit one or all of following settings

Code:

login_process_per_connection = yes
login_processes_count = 3
login_max_processes_count = 128
login_max_connections = 256

this what dovecot.conf do i use and what is exact sysntax?

I found:

Code:

/etc/dovecot/dovecot.conf
and
/var/run/dovecot/dovecot.conf 

Also tried

Code:

echo 256 > /proc/sys/fs/inotify/max_user_instances

thanks

 

ok think i have this worked out, but it also think it not the problem.

will make another post for that.

 

I'm having the same issue

We get these errors on the email server every day. I increased the login max process once and it broke the email so I took it back.

How do I increase my login max processes with breaking my email server? am I being invaded by spammers or other people that would increase the logins? I have a large user base so this server needs to be able to handle the logins to the email server.

Thanks in advance
