No, sorry, I need the port to be open for mail handling...
telneting to the box isn't different to a normal smtp connection. If you stop telnet, you also stop normal smtp clients.
Hmm, the point is, that I have heard some talking about something like a SMTP-proxy (?), which IIRC was meant as one machine acts like a firewall and "filters" and forwards mails to another machine, which is the Mailserver. I´m not sure if this is the right description (its a pretty long time ago), but maybe it could help you help me. Could this chain of 2 machines possibly be simulated by a forward-policy in my iptables-rules? Thx and have a nice weekend Enrico --
