David Southwell:

If would do that, then you would also need an unlimited disk
for the mail queue.

For safety reasons Postfix will not accept mail when the amount of
free space in the queue is less than 1.5x message size limit.

Enable submission in your (with "-o message_size_limit=0" as
an additional option), and have your internal users send mail via
submission (port 587/tcp) instead of plain SMTP.

message_size_limit = ########

####### is in bytes

This affects all messages though - if you need different limits for
outgoing and incoming, I think you'll need a policy server...

Yes, a policy server and an FTP client running as a policy daemon. ;)

There's no such thing as "unlimited". Pick a sensible limit that works
for you and your correspondents, and understand that most sites will
not accept unreasonably large messages, so don't expect to deliver 1GB
attachments to any recipients outside your domain any time soon.
