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?
