Today's upgrade moved the relay mailboxes from our mail server here to the mail server for the same system on which the Comm Center forum itself is running. Thus, the incoming mail messages for the forum go straight to that system and are picked up by the forum without travelling over another Internet connection.
The result is that the posting and reply addresses for the forums have changed from comctr.dc3.com to forums.dc3.com. This means that if you reply to old messages, the replies will now bounce since comctr.dc3.com is no longer. I apologize for this inconvenience. You'll soon forget about it though :-) I've updated the main post at the beginning of the thread with the new forum posting addresses.
