Unhappy postfix + courier pop outlook problem

I've a Debian mail server with Postfix and courier for pop3 connection,

when I try to connect on a pc outlook fault with error 0x800ccc90
Mac users are ok, and I've already Imap port thath works fine.

I've tried to change iptables rules, postfix conf and courier conf, but the error remain.

I think the problem is on the iptables or on the outlook type of authorization
