When I use sendmail on a specific message (/usr/lib/sendmail -v -qI082104)
the response from lmtp is to defer the message. This specific message
has fifteen or so people in the To:. If I release a message to myself,
or to anyone, where that person is the single person on the To:, the
message goes through. I wonder if somehow my integration between cyrus
and ldap is off somewhere. If the ldap is off, how do I tell for which
user the LDAP is off?
