--- Comment #6 from Jeremy Harris <[email protected]> ---
$max_received_linelength is already populated with the relevant value.
This can be checked in the smtp_data acl and the smtp transports:

acl_check_data:
 deny    condition  = ${if > {$max_received_linelength}{998}}
...

remote_smtp:
 driver = smtp
 message_size_limit = ${if > {$max_received_linelength}{998} {1}{0}}

Doing the latter results in a bounce for a long-line message accepted via
non-smtp and routed to an smtp transport.  You could reject in the non-smtp
acl instead, but if support for long-lines in non-smtp traffic is desired
this would be complex to properly filter.

Possibly we should add the above to the example configuration file.
