Imap/pop3 not working correctly


IMAP not working correctly. every 10 min restart Dovecot then work.

How I will fix it without everytime restart Dovecot

Please help me.


Check logs first …

master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped

I found this from log.

How can fix it and increase unlimited

Please help me

Edit file /etc/dovecot/conf.d/10-master.conf and add directive process_limit with the amount of processes you want to use (by default the limit is 100) to service imap-login.

For example, if you want to raise the limit to 200:

service imap-login {
  inet_listener imap {
  inet_listener imaps {
  process_limit = 200

Don’t forget to restart dovecot after the change:

systemctl restart dovecot
