This, unfortunately, is a conflict between two standards. Let me
quote from RFC 976:
However, a hybrid address
with a ! to the left of an @, such as a!b@c, is ambiguous: it could
be interpreted as (a!b)@c.d or a!(b@c.d). Both interpretations can
be useful. The first interpretation is required by RFC-822, the
second is a de-facto standard in the UUCP software.
The solution is to avoid hybrid addresses, but making sendmail change
its behaviour in such a fundamental way is likely to be a bit of
nightmare.
Actually, it is just one line of the rewriting rules:
# UUCP must always be presented in old form
R$+@$-.UUCP $2!$1 u@h.UUCP => h!u
If there were a way to put "parentheses" around $1 so that the domain
address it contained were ignored by the outgoing mailer, then everything
would be just fine. I am not that familiar with the various RFC's on
mail addressing, but I didn't happen to see any provision for such
parentheses. Is there any?
