parallel processing with procmail

[Pedro Sam <p2...@yahoo.com>]

Hi all,

Currently, I use a procmail script to process incoming messages like so:

:0fw: spamassassin.lock
* < 256000
| /usr/bin/spamc

I noticed that although I have 5 spamd children, only one of them was getting 
called at the time.  Does anyone know how to process incoming mail in parallel 
using procmail?

Thanks,
Pedro

I see. I thought the problem is that only one mail is fed to Procmail
at a time. Sorry for the confusion.

Sure.  Remove the lock that keeps the spamc calls serialized.

Typically people include the lock on the assumption that multiple users will
receive mail at the same time, and they'll all only make 1 request at a time.
A cheap "fair-queue" type thing.

I think you should look at your MTA, Procmail can't do a thing about it.
