Dear Friends, I have faced below issues since two weeks to till now. Could anyone help me to rectify this issue.

Below message retrieve from logs and getting disconnection from Outlook and other email clients.

Error Message

Jul 20 10:33:35 master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped

My local.conf from dovecot folder

protocol imap { imap_client_workarounds = "delay-newmail" mail_max_userip_connections = 20 default_process_limit = 300 } This should be just "process_limit" without "default". But it's unnecessary, as you set globally default_process_limit.

10-master.conf

default_process_limit = 300 default_client_limit = 1000

service imap-login { inet_listener imap { # process_limit = 15 # client_limit = 300 #port = 143 } It is the "imap-login" process_limit that is reached. With the set default_process_limit=300 this shouldn't happen. So maybe there is some setting somewhere else, that is not shown. Please supply the output of:

doveconf -S | egrep '(default|imap/|imap-login).*(limit|service_count)'
