     I experienced the same problem about 8 months ago.  I finally
found that the Sun was not terminating its lines with a CR,
while the Symbolics was waiting for one.  I've modified my
sendmail.cf to have two different ethernet mailers, as shown:

############################################################
#####		Ethernet Mailer specification

Mether,	P=[IPC], F=CDFmMnRsuX, S=11, R=21, A=IPC $h
S11
R$*<@$+>$*		$@$1<@$2>$3			already ok
R$+			$@$1<@$w>			tack on our hostname

S21
# None needed.


############################################################
#####	Symbolics Mailer
#####	Send to local lisp machines, with lisp domain rewriting.

Msymbolics,	P=[IPC], F=CDFmMnRsuX, S=12, R=22, E=\r, A=IPC $h
# Sender rewrite.
S12
R$*<@$->		$1<@$2.autocross>
R$-			$1<@$w.autocross>

# Recipient rewrite.
S22
R$*<@$->		$1<@$2.autocross>
R$-			$1<@$A.autocross>



     The determination of which mailer to use is controlled by
ruleset zero.  It has been given a list of Symbolics machines, as
a class.  A rule has been added:

# Delivery to one of the symbolics machines.
R$*<@$=A>		$#symbolics $@$[$A$] $:$1

This specifies the symbolics mailer for any machine in class A,
which is defined at the top of the cf file.  The square-bracket
construct in the right-hand side causes the lookup of the given
hostname in /etc/hosts, and its replacement with the formal
hostname.

     The domain rewrite rules were necessary at our site because
the Symbolics identifies themselves as being in a different domain
than the Sun system.

     Hope this solves your troubles,
