Exchange 2003 NO External email incoming until I reboot
Posted on 2012-04-06
We are running Exchange Server 2003. Starting yesterday morning we were unable to receive external emails coming in, but we can send out to everybody, and the email works great inside the intranet as well.
Our Antespam provider forwards our email to us and they say that they are seeing hundreds of lost connections and dropped connections.
When we reboot the Exchange server everything works fine for abut an hour or two and then it stops receiving again.
Any help would be greatly appreciated.
