Can SA be used to implement greylisting?

["Steven W. Orr" <st...@syslang.net>]

I'm running sendmail here on a home server. I've been looking for a good 
greylist package and I frankly have not found one. There are a couple out 
there but they work in memory and don't maintain their tables in a 
database.

I'm also running spamass-milter which is set to reject mail ifd SA says 
it's spam. Is it worthwhile to try to convince the SA dev crowd to add 
greylist functionality? I know it would be easy to modify spamass-milter 
to return the needed info to sendmail. It would require a new table.

Does this make sense?

My greylist code <http://whatever.frukt.org/mimedefangfilter.text.shtml> using the milter MIMEDefang <http://www.mimedefang.org/> keeps the tables in a SQLite database (wich means it shouldn't be too hard porting to a server based SQL database).

One of the key benefits of "normal" greylisting is that it you don't need to call SpamAssassin, anti virus stuff, etc, at all for the messages that never makes it through a SMTP level grey list.

Also, SpamAssassin cannot itself refuse to accept a mail, so the SMTP software still has to be involved for grey listing to work.
