Sendmail Max Message Size

[Thom Paine]

I thought I'd ask this question here before I post elsewhere and I
don't subscribe to the sendmail list and I would think other people
use this feature.

I'm looking to have a max message size that my one server accepts of
4M. However, I have a group of users who need to be able to bypass
this limit as they regularly receive email attachments of surveillance
videos that can be as large at 10M.

Is there a way to define a message size of 4M for everyone else except
for this group?

Thanks.

You'd have to set the max message size to the max allowed for any user,
and then write a custom check_rcpt ruleset to check ${msg_size}.

Alternately, there is a Maxsize field for mailers (I don't know when
sendmail checks it though); it may be possible to use a mailertable to
select a different mailer for some users with a different size. You'd
still have to set the overall max message size to the max allowed for
any user and then lower it via the mailer field.

Thanks for the reply Chris.

This gave me an idea to use in conjunction with MailScanner. I set my
global max message size to 10M and then created a ruleset to limit
other users to an even smaller size.

Thanks again.

I don't speak for anybody but myself - that's enough trouble.
