When you set the Local Mailer to CyrusV2 because you wish to deliver all
mail to the Cyrus store, the border Sendmail will accept and message
since it doesnot know which Cyrus User is actually existant.

The second sendmail process then actually talks to the lmtp socket of
the Cyrus Mailserver and learns if the user exists or not.
