[Mimedefang] Error on huge (~180mb) e-mail

[Nate Carlson]

Hey there,

I've got a client who's waiting on a huge e-mail (yeah, I've already
explained that e-mail shouldn't be used to transfer large files, blah blah
blah), every time the queue host tries to transfer to the client's mail
server (running Mimedefang), I get the following:

Jul 26 10:51:28 gatekeeper sendmail[6520]: g6QDmQ8u006520: from=<sender at example.com>, size=179151651, class=0, nrcpts=1, msgid=<B080C49E51C8D21183710008C739BE8F0147E377 at bvnts02>, proto=ESMTP, daemon=MTA, relay=mailq.domain.com [xx.xx.xx.xx]

I've got my timeouts set to really long periods (200min), and set up
Mimedefang not to run spamassassin across anything larger than 64k, and no
virus scanning on attachments larger than 5mb. Anyone have an idea what
this error could be?

Sendmail 8.12.4 and MD 2.15 on this box..
