I'm having still mail problems with some servers - mainly in Germany but
there may be others elsewhere. We are running Tinydns.
Could you please comment ?
I checked the domain daadjp.com against the following name servers:
a) our own (ns.choicenet.ne.jp = tokyo.choicenet.ne.jp,
ns02.choicenet.ne.jp)
b) merlin.daad.de (bind 8.1) - seems to have a timeout of 2 secs
c) deneb.dfn.de (bind 9.2.3)
d) mail1.rrz.uni-koeln.de (bind 9.2.3)
dnsq tests (Tinydns check program)
----------------------------------------------------------
a) dnsq mx daadjp.com 203.141.151.81
-> finds mail.daadjp.com and mail02.daadjp.com
b) dnsq mx daadjp.com merlin.daad.de
-> answer: 1+0+2+1, but no MX recs returned
c) dnsq mx daadjp.com deneb.dfn.de
-> 500 bytes: answer: 1+0+13+14, but no MX recs
d) dnsq mail1.rrz.uni-koeln.de
-> 171 bytes, 1+2+2+3 recs, MX and NS returned
dig tests
-------------
a) dig mx daadjp.com @203.141.151.81
-> flags: qr rd ra, 1+2+0+0
-> MX recs returned
b) dig mx daadjp.com @merlin.daad.de
-> 2 servers found, connection timed out, no servers could be
reached
c) dig mx daadjp.com @deneb.dfn.de
-> 1 server found, flags: qr rd , 1+0+13+14
d) dig mx daadjp.com @mail1.rrz.uni-koeln.de
-> 1 server found, flags: qr rd ra, 1+2+2+3
-> MX and NS recs returned
Every help is appreciated!
