I have a single mailbox mail server running Dovecot/Postfix and I have two IMAP clients, Thunderbird on the PC and K9 on Android. I keep on receiving this error in my logs even after I change the 'mail_max_userip_connections' variable to 50.
puppet dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10): user=<email@example.com>, method=PLAIN, rip=22.214.171.124, lip=126.96.36.199, TLS
Why does it say that it is set to 10 in the log? Is that hardcoded?
grep -r "mail_max_userip_connections" /etc/dovecot /etc/dovecot/conf.d/20-managesieve.conf: #mail_max_userip_connections = 10 /etc/dovecot/conf.d/20-pop3.conf: #mail_max_userip_connections = 3 /etc/dovecot/conf.d/20-imap.conf: mail_max_userip_connections = 50
I've restarted dovecot after making the changes but this error is still logged and I can't access the mailbox. Can anyone help me understand why I can't seem to raise the maximum limit?
