SBS 2003 w/Exchange 2003 fully patched.
Since I have applied the latest round of patches, no mail has left this server. The message I get when looking at the queues is "The remote server did not respond to a connection request." I've been looking all over the Internet and have not found anything that may help me resolve this issue.
I've not gotten any event log entries yet as none of the messages have timed out. It is not selective--all messages sit in the ueues. Any suggestions?
I can TELNET into various of the mailservers giving me a problem. I have run SMTPdiag successfully against others. Worth noting is that Yahoo! took a long time to give replies with two of the mail servers listed in MX records timing out. Both were run on the affected server.
I am beginning to suspect the linksys router I have in place. I have known them to fail in strange ways. I'll not be able to get a replacement until at least tomorrow, if not the next day.
Perhaps worth noting, this started when my server was under attack by some cretin trying to relay against it to the tune of 5000 messages per hour. Also, this is my home server. Fortunately, I have other means of sending messages, and incoming mail does not seem to be affected.
