Sendmail and DNS are two entirely separate entities and sendmail doesn't
"check" DNS to see if its supposed to be a backup mail server. From your
message, DNS appears to be doing its job - namely providing the IP address
of your backup mail server in the event the primary one is
unavailable. Sounds like the problem is with one of sendmail's
configuration files. My backup mail has an entry in
/etc/mail/relay-domains, my /etc/sendmail.cw file is empty and I did "roll
my own" sendmail.cf file using the m4 macro processor, but I don't remember
any funny rulesets. I *think* the location and names of some of the files
changed between 5.2 and 6.2, so you may want to use the m4 macro processor
to create the sendmail.cf file and point it at the correct files.
