No, there is nothing in the RFCs that says this is incorrect (unless it
is in the phrase part of a ``Full Name <address@domain>'' syntax address,
which was the problem with the ``Mr. Foo Bar <foobar@some.where>'' that
appeared a few days ago).

It is possible to configure sendmail to use dots in the local-part (that
is, the left hand side of the @) in different ways, but most sites do not
do this.  I suggest using ``sendmail -bt'' to track down what it is
really doing with these names.

Old Berkeley sendmail.cf files would cause the problem you are having
because of the (now long dead, at least at Berkeley) BerkNet syntax.
This was originally ``host:user'', but colons ARE illegal in local-parts,
so we had sendmail map dot to colon so that ``host.user'' would become
``host:user''.  Newer config files do not do this.
