Say you have an email alias pointing "webadmin" to "localuser".  An
email delivered to "address@hidden" won't get processed with the
right user rules, since there is no "webadmin" account.  You need to
ask sendmail what a particular address expands to, and -bv is the only
way I have found.

Yes, I'll probably have to do both.  Although compared to the cost of
running spamassassin at all, the time spent running the 2nd sendmail
copy is probably in the noise.
