If you insist on doing Rabid Rerouting (a controversial decision I see
no point in discussing here), then this looks like a good way to do
it, except that I would replace all of the "$*" elements with "$+"
to keep from rewriting such obvious garbage as "!.!@".

I believe the original question was simply how to change
"host.domain!user" into "user@host.domain", with no suggestion that
rerouting was desired.  Here is one way to do it in sendmail:

R$+.$+!$+		$@$3<@$1.$2>		resolve mixed UUCP/domain

It belongs near the end of ruleset 3, *after* this rule:

R$*<@$+>		$@$1<@$2>		already canonical

Note that if either of these rules is applied it will result in the
current ruleset being exited.  Your usage may vary.
