Hi, I use a gateway router with firewall on SuSE 7.0. There is sendmail installed. I try to route all incomming e-mails, (smtp) from my provider, directly to a Exchange-Server in my Domain. I realized it with SuSE 6.4 and had no problems. Now I get authentications-warnings. in /var/log/mail (if sendmail is running or not) No mail is going to the Exchange-Server. Is there a problem with sendmail on 7.0 ? I think my internal interface has no open port for smtp (25) to route to the exchange. Does anybody has a idea what I can do ? I tried every possible configuratin on sendmail or firewall.
