Hello everyone,
I have some really unusual things happening with my server since last Sunday.
I can no longer SMTP out to most addresses. I can't even telnet to these addresses via port 25. I don't know if it's my ISP (Symptico) or if it's my SuSE. If I try to telnet to a server via port 25, I get a no route to host. The system does get the proper address through DNS translation, but it fails.
Can you telnet to other ports, say port 80 on a web server for example? If so, then your ISP is filtering port 25
