You may want to examine the logs a little closer than looking for
'connect'. What else did processes 30863 and 30722 log for that
SMTP session?
IIRC when "MAIL FROM:" is rejected due to size limit overflow, there
is nothing to indicate this in the logs.
Hi Viktor,
Thank you for your reply.
Is there anything that I can look for in the Postfix config that may
lead to a size limit overflow, or is the cause something outside of our
control?
If the two are related (it doesn't sound like the two are), the
message_size_limit setting is configured as 76800000 and the health
checks being performed are for a very small amount of data.
