First of all, stop top-posting.  It's very confusing.

Second, if you really do have qmail running (did you verify using ps -auxw 
| grep qmail? that's only one part of troubleshooting your problem.

1) Is qmail actually running?
2) Is qmail configured to listen on FQHN:25?
3) Is port 25 blocked by your firewall?
4) Is port 25 blocked by someone else's firewall?
5) If all of the above is ok, is qmail not responding for some reason?

IOW, you have only begun to troubleshoot.  Saying im running qmail is 
meaningless.
