last week suddenly my gateway stopped delivering
emails only to extern, our Exchange told me this error:
XXXXX.XXX.XX #503 5.5.1 Error: need MAIL command ##
Then I created a new one with the backup settings of it and everything works fine again.
Today I try to find this error in the log files and did not see it on the gateway, also a
test mail works fine.
Any other person who has experience with that?
This sounds more like a (temporary?) network issue or some firewall issue.
The mail.log (MTA log) should provide more information.
Since you said that it worked again with a new gateway. Was the new
gateway the same version or newer release?
