[ILUG] get sendmail to reject mails over a certain size

[Declan Grady]

Hi again follks,
I have a sendmail 8.12.3 up and running with mailscanner, spamassassin, and
f-prot, on a redhat7 box. (at last !).

Is there some way I can configure either sendmail (or procmail ?) to reject
messages over a certain size ?
To confuse the issue, I would have a 'whitelist' of email addresses and
domains from which I should accept any size of message.

Ideally, I'd like to bounce the message back to sender, saying it was not
delivered, or it was quarantined, and also notify the intended recipient of
the failed mail.

I dont really want to force a quota on the mailbox size, as then the
important emails would be rejected, due to the junk filling up the mailbox.

I'm trying to filter out the 3 and 4 meg junk mails, which slow my mail
delivery to a crawl.
(Stil on a 56k modem, as I think it'll be a while before Crolly gets adsl !)

Any suggestions ?

Thanks,
Declan
