Hi,
We have a printer IP segment/VLAN which is only printers and these
printers are also scanners, and they email the scan back to the user.
Since the scan outputs frequently exceed the configured
message_size_limit of 7.5MB, in master.cf I configured a non-standard
port (2526) that is restricted to the printer segment and sets to
message_size_limit back to the default of 10240000.
So, this changes the size limit as reported by the Postfix SMTP
server. As of a few releases ago, the SMTP server will also enforce
the size limit, to avoid wasting resources sending too large mail
to a before-queue content filter.
Now, when I send an oversize message (6.2MB, not even that large), I no
longer get the message telling me that I have exceeded the 7.5MB message
size limit (6.2MB, when BASE64 encoded will more than exceed the
message_size_limit being bypassed), but instead, I am getting the
message from cleanup: "queue file size limit exceeded".
Indeed. The cleanup server implements the message size limit. In
early Postfix days, this was the only place where the message size
limit was enforced.

file size limit exceeded
I did a bit of googling, and all I found was to check the amount of free
space left in the queue and whether the message size exceeds
queue_minfree.
The message says that the queue file exceeds the size limit.
The message has nothing to do with free disk space.

Thanks. I defined an alternate cleanup_service_name and set the larger
message_size_limit and by golly gosh, it all works now.
