I did this with sql but the users have a seperate in and out max.
Say: /etc/exim/max_size containing:
me: 12m
you: 1m
them: 500k
In the rcpt acl if the $message_size is > 0 (NOTE: not all clients send the
size of the message).
You can use:
deny message = Too large
condition = ${if >{$message_size} \
{${lookup\
{$local_part}\
lsearch\
{/etc/exim/max_size}\
}\
{yes}\
{no}\
}
Change $local_part to $sender_local_part to check sender.
Use the same thing in the data acl for sender only. You can't (iirc) check
each recipient in the data acl. I used a redirect router to do this, same
check and used: data = :fail: too large
don't forget to use "allow_fail" in the router.
