I have one backup mx setup locally to my main Smartermail server, however it always responds with no such user.
I have a third backup mx offsite which seems to work fine.
Yesturday my main box went down because of Smartermails service crash, however no email was collected on my backup mxes.
I guess the email tried to go to my second backup mx which responded with no such user. And thats where it ended, nothing was sent to my third backup mx.
I do not know where to look to find clue as to why my secondary backup is not working...
any pointers would be great.
