Hello All!
I'm sorry for a stupid question, but there is one thing I can't
understand.
I have mail server (Exim 4.34) which is acting as a MX for a few
domains. And I don't want my MTA to accept messages larger than 10 Mb
(for example). Surely it can be done by setting the message_size_limit
option to 10M. But it applies to all the domains I am relaying mail
to and some domains have no such limit. So I've defined a new router:
max_size:
driver = redirect
domains = (domains...)
allow_fail
condition = ${if >{$message_size}{10M}{yes}{no}}
data = :fail: The message you are sending is too long.\n \
Max size if currently set to 10 Mb.
But recently I've noticed that some of such messages are rejected
during the smtp conversation:
"550 The message you are sending is too long."
But sometimes Exim accepts such messages, but generates an error
message which is returned to sender. Something like this:
-----------------------------------------------------------------------
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
user@???
The message you are sending is too long.
Max size if currently set to 10 Mb.
------ This is a copy of the message, including all the headers. ------
How does it decide whether to generate error message or not?
