Correct. You want main.cf message_size_limit to be larger than
"smtpd -o message_size_limit". But you need more than 82 bytes
difference if you want to be precise.
The Postfix message size limit is the size of the queue file. This
includes storage for the envelope sender, envelope recipient, and
some other metadata such as the arrival time, delay warning time,
content filter, and so on. That adds some 600 bytes of overhead
depending on the number of recipients and the length of email
addresses.
