SMG gateway - SMTP Protocol Returned a Permanent Error 552 Message size exceeds fixed maximum message size
When I send email to outside , I always get this error message if the mailsize is big,
SMTP Protocol Returned a Permanent Error 552 Message size exceeds fixed maximum message size
However, I have already checked on the mail server and smg smtp server and the maximum message size I have set to 20MB,
but actually my mail was around 8MB, still getting bounce back of the Error 552.
I updated the setting of SMG from here:-
Administration > Hosts > Configuration/Edit/SMTP tab, Advanced Settings -
Outbound SMTP Configuration > adjust the maximum message size on inbound and outbound already.
Do I have any more place to check?
