I usually do this at the level of the mailer section of the sendmail.cf.

The S= and R= fields in the mailer definition point at rules to rewrite
From: and To: to your specifications.

What I would do is define a class of hosts with the C macro and then
use a rule like this.

#define Class of special hosts
CS host1 host2 host3

#begin rewriting rule to take a specila host name out 
# this is probably more than actually has to be done
# comments welcome
# remembr the $w is defined as your local hostname
S31
R$=w!$+			$2				strip local name
R$*@$=w			$1				strip local name
R$=S!$+			$2				strip special name
R$*@$=S			$1				strip special name
R$*<@$=S>		$1				strip special name
R$*<@$=S.$->		$1				strip special name
R$*<@$->$*		$1<@$2.UUCP>$3			resolve abbreviations
# special case for UUCP mailer, may be different for ARPA
R$+			$:$w!$1

Anyway, this is the rewrite I use for the From: field.
Example mailer

Muucp, P=/usr/bin/uux,F=sDFuUM,S=31,
	A=uux -a$g -gC $h!rmail ($u)

Hope this is helpful.
