[sclug] sendmail dns question.

[Tom Dawes-Gamble]

Hi,

	OK you sendmail and DNS gurus what have I done wrong.

[root at jabog named]# nslookup -querytype=MX triv.org.uk 
Server:         127.0.0.1
Address:        127.0.0.1#53

Non-authoritative answer:
triv.org.uk     mail exchanger = 90 mail.makyo.org.
triv.org.uk     mail exchanger = 10 mail.triv.org.uk.
triv.org.uk     mail exchanger = 80 jabog.tmdg.co.uk.

on jabog.tmdg.co.uk I have added triv.co.uk to the
/etc/mail/relay-domains 

The other day someone sent a message to simon at triv.org.uk and I guess
mail.triv.org.uk was off-line or unreachable for some reason.  So the 
mail arrived at jabog.tmdg.co.uk and then jabog.tmdg.co.uk sent the mail
to mail.makyo.org who in turn sent it to jabog.tmdg.co.uk  and so the
look continued till it got "too many hops"

So what is wrong?  Surely jabog.tmdg.co.uk should not have sent the mail
to a host whose MX is greater?  (or equal for that matter).


jabog is a name server but not for triv.org.uk. 

hostname(1) returns jabog.tmdg.co.uk 

So what is wrong?

Tom.
