Hmm, I'm afraid you didn't look too hard.  Both my old BSD4.2 documentation
as well as the BSD4.3 clearly states this.

From section 5.3.6 of sendmail/doc/op.me:
# Finally, an argv template is given as the E field.  It may have
# embedded spaces.  If there is no argv with a $u macro in it, sendmail
# will speak SMTP to the mailer.  If the pathname for this mailer is
# [IPC], the argv should be
# 	IPC $h [ port ]
# where port is the optional port number to connect to.

In response to all those who have written and asked about the enhancements
to sendmail I promised to post earlier: Don't worry, it's coming.  The IDA
Sendmail Enhancement Kit will be released to comp.sources.unix the moment
I have finished the accompanying report and documentation, which should
happen sometime this or next week.  Thanks for your encouragement too, I
never knew the urge was this great for something of its kind.  I hope you
will like it just as much when you get it.
