I'd defer to the O'Reilly book at this point -- or run it by the lists
at sendmail.org.  You might watch out, though... The remote mail server
may refuse to send mail with a '+' in it, and it will never even reach
your server.

Finally, is this really a wide-spread problem?  There are quite a number
of different Email verification regexp strings in the PHP man pages --
there are a great number of different patterns, as you can see from this
page: http://www.php.net/manual/en/function.eregi.php -- If this problem
is limited to a small number of sites, you might inform their
webmasters, and they MIGHT fix the problem, and you won't even have to
look at the Sendmail configs...  That's always a plus. :)

In the meantime, I would probably do something like this in the aliases
file as a patch:

addressforbrokenwebpages:    username-broken at example.com
