Hey,
I am having a problem with both of my Exchange servers. When I try to TELNET into the servers, both internally and externally on port 25, the command prompt window goes completly blank. It does not recognize anything I write in the window and after some time I am thrown out.
When I try to telnet into port 110, the exchange server reply's immediatly with "Microsoft Exchange Server 2003 POP3 Server version 6.5.7638.1 ready
What could the error be?
For the sake of the question both ports are open in my firewall (Zywall 10), the mail system works fine, and has been working fine since the last install (approx 20 months ago). But with some problems.
1. Users have reported that mail dissapear, and no feedback is given? This might be the ISP which scan's our mail for virus.
2. I have a copymachine which cannot use the internal server as smtp server. When it tries to connect the connect is fault in some way.
Hope for some answers that can fix my problem. I give this top priority since I am switchin supplier of external virus scan services tomorrow, and I need to fix this problem for both servers.
Best regards,
Marius
