Pretty much what it says. An incoming mail will be refused if its size
exceeds message_size_limit (in bytes). It is undocumented (and not
recommended) to use message_size_limit=0 meaning 'no limit' - although
mailbox_size_limit=0 is valid/documented.
Although your postconf is reporting 23240000 (a little over 22MB), you
can (and may) have different settings in master.cf which override this
- for instance for authenticated vs non-authenticated incoming mails.
note that some SMTP clients don't check SIZE option your SMTP server sends
to them and some don't announce the SIZE in MAIL FROM command.
You would not see this message otherwise :-)
