Hi!

I am trying to make Windows 8 using Live 2012 and Outlook 2010 login in Dovecot POP3s. However, I receive this message in log:

Feb 28 07:32:05 ipanema dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=10.0.0.10, lip=10.0.0.1, TLS handshaking: Disconnected, session=<joP78nTz9ACsFQAF>

Note that user is sent as blank and this is the only log line. I used debug mode too:

Analysing the traffic with tshark, I can see:

0.007163 10.0.0.10 -> 10.0.0.1 TLSv1.2 331 Certificate, Server Hello Done

I am using Dovecot 2.2.9 and I think it is TLS compatible. External (non-MS) clients, as Mozilla Thunderbird and Sylpheed, are working fine.

Can someone point me a light?

# 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 ext4

Thanks in advanced.
