I ran into some problems with 'Fang 2.3 Beta 1 (prior to your 
submission, Jeff) and after a bit of reasearch (the 
Mail::SpamAssassin::PerMsgStatus man page) I found the 
$status->finish() call.  I put it in David's spam_assassin_is_spam 
function, just prior to the return call, and it seemed to eliminate 
my problem.  Would it be useful to add this to your functions as 
well?

What would be the impact of making these global variables (similar to 
$VirusScannerMessages) within mimedefang.pl?

How much access is there to sendmail variables, etc. within a milter 
script?  Is there any way to leverage the sendmail internal map 
files?  I'm thinking specifically of the FEATURE(delay_checks) stuff 
which results in /etc/mail/access.db lookups for "SPAMFRIEND" or 
"SPAMHATER" values.  I use this for turning RBL checks on and off for 
particular users, and it would be handy to add/edit users in only one 
place.
