Since a few days IMAP stopped working. I tried adding a domain and mailbox from scratch but these also don't work. Webmail, sending and recieving works fine. When adding an account in outlook it seems to just time out. I see in the ISPCONFIG logs that the account logs in and instantly logs out in the same second. (twice to add to the confusion) Code: May 14 16:31:10 hosting dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=::1, lip=::1, mpid=14395, secured, session=<+/dd4tmIroIAAAAAAAAAAAAAAAAAAAAB> May 14 16:31:10 hosting dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=::1, lip=::1, mpid=14396, secured, session=<dg9e4tmIsIIAAAAAAAAAAAAAAAAAAAAB> May 14 16:31:10 hosting dovecot: imap([email protected]): Logged out in=318 out=2042 May 14 16:31:10 hosting dovecot: imap([email protected]): Logged out in=120 out=766 I'm running Debian 9 with the latest ISPconfig and all are up-to-date. Tried it with 143 and with 993 and SSL. Are there any other places where I can look to see why IMAP isn't working anymore?
What you see in the log is from webmail, so that's ok. maybe imap port is closed in a firewall so you can't access it from outlook but it will work on localhost (webmail) then.
