    1)  Having fetchmail use SMTP is not a very good idea, instead use
        the option
            mda = /usr/sbin/exim %T
        in your .fetchmailrc.  It's much more reliable that way.


    2)  mutt doesn't do SMTP (because it's a MUA, not an MTA).  It
        pipes the mesasge to $sendmail (defaults to /usr/lib/sendmail,
        which is a symlink to exim) because it is simpler and more
        reliable.


        Due to your setup, this means that mutt hands the message
        straight to exim and avmailgate never sees it.

Does avmailgate have a command-line interface? Particularly one that
takes a message on stdin and echos it out (tagged in some way) on
stdout?

If so then you can use this strategy
    http://dman.ddts.net/~dman/config_docs/exim3_spamassassin.html
and substitute avmailgate for spamc in the exim config part of the
doc.  Also, accordingly, substitute the checks in the system filter
for whatever tag avmail uses (instead of X-Spam-Status:).


Another possibility for you is to use exiscan. (do a google search
for it)

HTH,
