[Dovecot] dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections)
by David Brown 04 Mar '13

04 Mar '13

Hi, has anyone seen this issue before as I have not. I'm a long time dovecot user and I don't see anything in the config that should cause this. The mail.log gets hit a lot of times with this same log message: dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections) I have noted that it is more evident when I try to mass delete many messages. Any ideas of how to diagnose this issue? The dovecot -n follows: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.1-rscloud x86_64 Ubuntu 10.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 5 login_max_processes_count: 256 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mbox_write_locks: fcntl dotlock auth default: realms: davidwbrown.name default_realm: dobbeltganger.com username_format: %n verbose: yes debug: yes debug_passwords: yes passdb: driver: shadow userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] dovecot proxying with imapc
by suja 04 Mar '13

04 Mar '13

Dear sir, I have to set up a mail gateway which will be explored to Internet and a secure mail server in the Intranet. I need a smart imap proxy in the mail gateway which will fetch the mail from server and present to user through either a stand alone mail client or a web mail client. All authentication is through ldap server. I followed the instructions given in http://wiki2.dovecot.org/HowTo/ImapcProxy But while logging in I am getting a error: dovecot: imap(user1): Error: user user1:Initialization failed: Initializing mail storage from mail_location setting failed: Unknown mail storage driver imapc dovecot: imap(user1): Error: Invalid user settings. Refer to server log for more information. I couldn't figure out what is wrong. Please help me to sort it out.
