Hello, First of all, I'm sorry if you received this mail twice; I haven't received it the first time so I think it was lost. Second attempt.
I've made some more tests and I still can't receive mails. Outlook doesn't complain about anything, no error message; the mails that are supposed to be received just won't appear. In the mail logs, I find this line (other lines are irrelevant): dovecot: imap-login: Aborted login (no auth attempts in 2 secs): user=<> [...] Is this a problem that looks familiar? It's a bit clueless without an error message. Any idea welcome.
