Yes.  The sendmail.cw file specifies which hosts should be treated
the same as localhost, so it would try to deliver.

The backup servers should not specify each domain in sendmail.cw; rather,
RELAY_DOMAIN_FILE should be used in your .mc file and populated with
domain names to queue.  If the MX records are right, it will only queue
until the primary becomes available.
