As ever, though, when using procmail to send mail out, you
should first append an X-Loop header, and of course be testing

Come to think of it, we can check for X-Loop's existence
in the very same rcipe, killing two birds with one stone.
:0 fw h
* ^Return-Path:.*<\/(_dot_)*(_at_)domain1(_dot_)com>
* $! ^X-Loop:(.*\<)?$\MATCH?$
* MATCH ?? ^^\/[^(_at_)]+
| formail -I "X-Loop: $MATCH(_at_)domain1(_dot_)com"
:0 a # implies A
! $MATCH(_at_)domain2(_dot_)com
Note that I'm using the "?" in the second condition to
effectively get rid of the ">" even though it's still there. :-)
Here's an alternative:
:0 fw h
* ^Return-Path:.*<\/(_dot_)*(_at_)domain1(_dot_)com>
* MATCH ?? ^^\/.*[^>]
* $! ^X-Loop:(.*\<)?$\MATCH$
| formail -I "X-Loop: $MATCH"
:0 a # implies A
* MATCH ?? ^^\/[^(_at_)]+
! $MATCH(_at_)domain2(_dot_)com
One MATCH-reparse extra, but probably algorithmically cleaner.
