I have two emails that have been stuck for days in the spool of my backup mx smartermail free install.
By the look of things my backup seems to be trying to send to itself, which must be a bug as I did not notice this behaviour before:
601 Attempted to send the message to the following ip's: *primary IP, *backup IP
Because of the multiple attempt to send to itself my primary mail server will not accept the emails saying the max hop count was reached:
data transfer failed. 554 Maximum hop count exceeded. Possible loop.
Whats going on here?
