Sendmail continues to deliver with procmail.  The difference when using 
mimedefang is that you have already rejected viruses and spam with high 
enough scores to reject early in the smtp conversation, and 
spamassassion only needs to run once on messages with multiple 
recipients.  You can add a header with the spamassassin score, then 
filter/sort on that in procmail (or pop/imap agents) so users can have 
different handling of the same message.  The mimedefang operations are 
controlled by a small  snippet of perl so it is easy to customize.
