another sendmail problem

[Paola Formai]

Hi,

I am configuring a new sendmail.cf on my new Hp 9000/835S.
Hp talks to the Italian network backbone site via a dialup uucp link;
I configured sendmail.cf in such a way an address as:
	user at host.domain
is routed, via uucp, to the backbone.

The mail is correctly delivered to the backbone site BUT each user
receives back his/her mail with:

----- Transcription of session follows ------
554 No ! in UUCP! (paola at hp.UNIMI.IT)

----- Unsent message follows -----
etc. etc.

How could I avoid this annoying thing?

On my old Vax 4.3BSD with a similar sendmail.cf all works really fine
and the user does not receive back his/her mail. The only notification
of the use of the syntax user at host.domain instead of host.d!user is
in /usr/spool/mqueue/syslog.

Ciao.
