[Techtalk] Courier Mail + Debian

[ellie]

Greetings.  I have a mail server running Debian at work; it uses Courier for IMAP, POP3, and ESMTP.  Everything is working nicely, and I am very happy with Courier.  Recently, however, one of my users tried to send 24 MB of attachments to me.  She was unable to do so, and when I tried to replicate the problem using my own account, I was unable to send a 10 MB attachment.  Appearing in /var/log/mail.err was this error message:

523 Message length exceeds administrative limit

I looked this up on Google and found only a few related pages on this problem.  What I found was that people had gotten around this size limit by specifiying the limit at the time that they compiled Courier.  I installed Courier from a Debian package though, so I'm not sure how to redefine the limit at this point on my mail server.  Courier has a lot of documentation, and I'm not always certain where to look.  I'm hoping someone will have experienced something similar and will know of a possible solution.  Thanks in advance to anyone who might have an answer to this problem!
