I've a Debian mail server,
but only the outlook users can't be able to download the emails.
I've seen a lot of post about some kind of
forwarding port configuration, I've tried some commands, but I don't be able to solve this problem,
please help me.
[LAST UPDATE]
I find a lot of TIME WAIT on ipv6
netstat
tcp6 0 0 my.mailserver.it:imap2 200-62-245-188.ip2:17060 TIME_WAIT -
below some config files:
pop3d
I think the problem was here
