[Exim] Proper SMTP-time rewrite syntax?

Forgive my ignorance regarding regexps, but is this an appropriate one
to use to change domain1.com -> domain2.com at SMTP time? I need to do
this so the rewrite will occur before $domain is passed to one of my ACL's.

begin rewrite

\N^<(.*)@domain1.com>$\N $1@??? SEh

Thanks.
