should not be difficult to implement

dbmail has a setting after a feature-request from me because
the "smart" Apple Mail resulted in crashing the server multiple
times by a user on the LAN who draged the wrong attachment to
a new message which was a some GB large video and Apple insists
trying to save the draft each time the server comes back

dbmail.conf:
max_message_size = 36700160
