hi... i have a problem using my two mailserver (qmail & imail) in my DMZ. Any server can receive/send mails from his clients and receive mails from other MTA. But when a client send a mail to a non-local domain (a other MTA) they'll be dropped by a 'SuSE-FW-DROP-DEFAULT' - Rule. The MTA brigns then 'Error Stack Connect' or 'MX Connect Fail' (e.g. IMail). "Hmmm... then open port 25".... right, this is done. And I can sent email to any MTA over my customers virtual domain, but the customers can't do... Now my question is... what is wrong in my SuSEfirewall2 Skript??? Where can I look for? regards Alex
