procmail domain redirect

calling any/all procmail gurus:

is it possible to use a procmail filter to redirect email to another
domain yet preserve the userID?

@somedomain.com
redirects to:
@myserver.com
which preserves the original @somedomain.com in a
"Delivered-To:" header
The procmail's job is to redirect again to:
@anotherdomain.com

I would be able to do this just fine if the $MATCH feature allowed
"fencing in" the userID portion but alas, it always selects through the
end of the line

:0
* ^Delivered-To: \/.*@somedomain\.com
! $MATCH@anotherdomain.com

This of course doesn't work because @somedomain.com needs to be
stripped off first.

Help! :-)

You could change the address with sed

:0
* ^Delivered-To: \/.*@somedomain\.com
! `echo $MATCH | sed s/somedomain/anotherdomain/`

I hope this helps,

Tim in a subsequent email provided an option. Here is another:
:0
* ^Delivered-To: \/[a-z0-9.+_-]
! $MATCH@anotherdomain.com

Re: procmail domain redirect

Thanks so much, that worked! (As you probably knew!!) I had a feeling
it would require the use of sed, awk or somesuch thing, but I'm not
completely up to speed on what you can do in a procmail delivery line.

Thanks again!
