Sorry for not posting a work-around when I first described the problem.
Since sendmail is looking for an '@' in any recipients that use the tcp
mailer (this is the bug), you can fool it by adding a source route in
ruleset 0 where the uucp relay is handled.  This is the diff to sendmail.cf:

171c171
< #DUHostWithModems
---
> DUlopnor
1024c1024
< R<$+>!$+                $?U$#tcp$@$U$:<$1>!$2$|$#uucp$@$1$:<$2>$.
---
> R<$+>!$+                $?U$#tcp$@$U$:<@$U:><$1>!$2$|$#uucp$@$1$:<$2>$.
                                        ^^^^^^

Where the "<@$U:>" source route satisfies the check for the '@', while the
uucp relay host ($U) should recognize it as itself and just strip it.

Please let me know if there are other problems that this doesn't fix.
As I said before, the bug will be fixed in the September update.
