Can you successfully telnet to port 25 on mail.simail.it from the Mailman server? No If you can connect (via telnet) to port 25 on mail.simail.it from the Mailman server, then I'd suggest stopping and restarting Postfix.

if i try from the mail server i get

telnet mail.simail.it 25 Trying 217.27.113.30... telnet: Unable to connect to remote host: Connection timed out

mail.simail.it is ignoring your mail server. This is not a Mailman problem.

1. Check to see if that server has a stated policy for "abusive" mail and some way of getting back in their good graces.
2. Check if your mail server is in the RBLs. Some of them are very aggressive about adding IPs and domains.
3. Try writing the postmaster at mail.simail.it.
4. Ask your subscriber(s) at mail.simail.it to write their postmaster.
