Sendmail message size limit per domain

Leovino A. Trinidad, Jr — Sat, 27 May 2006 09:20:23 GMT

Hello!

My superior would like to limit the size of the mails per domain... how can i do it in sendmail acting as a mail relay? I 've tried duplicating the mail agent and add the M= option but it doesn't work... so I think the best option is a rule for it... I am not versed in rule... I appreciate any help from you guys.

Regards,

LAT

You can do this with milter-length : http://www.snertsoft.com/sendmail/milter-length/.

Vitaly suggestion is good. Just expanding on it a bit.

Sendmail, whilst it can be set up to accept for a wide variety of domains, protocols, and with vast amounts of options, have no nice rules for messages size limits.

It has *ONE* option:

O MaxMessageSize=

This applies to all incoming mails, as well as all outgoing mails. It's granulated enough to do a per-domain size limit.

So yea, look at a Milter. We use custom (perl) milters to limit message size (and other things) by user class. It's pretty easy to do (even easier as there is one written already).

Good luck! :)
