Mail service on, SMTP on, but clients can't connect -- please help a novice
We use 10.4 Server on a G5 Xserve. A few days ago we had a problem with our server being used for spam. That was fixed quickly enough, but the problem is: while being fixed, the mail queue accumulated more and more mail, and it wasn't going out. The "retry" button didn't work. Repairing the database didn't work.
To make a long story shorter, after reading different things here and on the web, I managed to delete all the messages in the queue. All the users are still there. But now, when I turn the mail service back on, everyone gets a "can't connect" error.
I've used the terminal before, but I've always been following directions; I don't know what to type or why. But if someone with patience can help, I can follow directions, and would really appreciate the help. Right now I'm dead in the water.
