Just did a SBServer2003 migration. mail is not working very well though. I seem to have a problem with port 25 staying open.
At various times of the day mail gets delayed by hours. just a simple hotmail test, which goes through normally very fast, sometimes never gets delivered.

I ran a GRC shields up test and sometimes it come up open and sometimes closed. sometimes I can telnet externally and sometimes not. I already replaced the router because I thought the forwarding wasnt working. Apparently that wasnt it.
I have been working on this for about a week and its killing me. This is for a customers site and thier emails are getting lost.(not rejected, not stuck in queue) just lost. any Ideas would definitly help me out.

thanks alot,
Ryan
