Help converting from procmail to qmail

[Scott Ehrlich]

I recently moved my domain name from my home debian machine to pair.com.

On my home machine, I had a .forward/.procmailrc setup.  The .procmailrc
recipe was:

:0bc:pager1$LOCKEXT
* ^Received:.*source_domain.com
| /my/home/dir/path/to/script


This successfully caught an incoming message from a particular source
email address, sent a copy of it, and forwarded a copy to a shell script
in my home directory.

pair.com uses qmail, so I now need to learn how to translate the above to
a .qmail file.   I also don't want to lose any email in the process.

Help with the conversion would be helpful.  It is a simple recipe, so I
cannot imagine it would be difficult, though it did take me a bit to get
the above recipe working perfectly the first time I set it up :-)

Thanks for any insights.
