[Dovecot] I gonna understand one day

[ohp at pyrenet.fr]

Hi,

I'm still struggling with dovecot and Unixware:
On my main server, I have two problems:
1- imap-login has great difficulties to connect to 'default'.
I have traced it to accept in auth_master_listener.c witch fails with
errno=71 (EPROTO) weird...

2- It some times works and I can log-in but imap gets killed by signal 6
(abort?)

See the logs:
