I have two servers where I've deployed a Webmail (squirrelmail+avelsieve). One of them has direct conection to the sieve server, and works without problem. The other one is behind a firewall.The only thing we get when we do a telnet is: telnet THE.MAIL.SERVER 2000 Trying .THE.MAIL.SERVER .. Connected to THE.MAIL.SERVER . Escape character is '^]' Does sieve has any special requirments to go through a firewall?
