My problem: Some mail addressed to jpotter at falcon.lhup.edu is NDR
by cardinal.lhup.edu.
The desire: (I think) Mail to user at falcon.lhup.edu should be delivered
to falcon. Also any other machine. Mail to user at lhup.edu should be
delivered to cardinal. If user has no box on cardinal, it will bounce,
but that is ok.
The DNS:
lhup.edu 3600 IN NS starling.lhup.edu
lhup.edu 3600 IN SOA starling.lhup.edu administrator.lhup.edu(
110 ;serial (version)
3600 ;refresh period
600 ;retry refresh this often
86400 ;expiration period
3600 ;minimum TTL
)
lhup.edu 3600 IN MX 10 cardinal.lhup.edu
lhup.edu 0 IN 65281 ???
Additional information:
starling.lhup.edu 3600 IN A 151.161.44.11
cardinal.lhup.edu 241 IN A 151.161.11.3
falcon.lhup.edu 3600 IN A 151.161.11.6
Other info:
falcon aix/sendmail
cardinal nt/exchange
One outside mailer outlook express for mac
Questions:
1. Sould the DNS work for all external mailers?
If so, the senders have a problem.
2. If not, what entries would allow the desire?
3. If the above is valid, could cardinal exchange settings cause
the problem anyway?
