Nslookup Set vc (to force TCP which is I think SMTP's default lookup
Hi guys - has anyone noticed anything funky with Xtra's DNS over the last 2 or 3 days? I have a client that had periodic mail buildups on outbound SMTP and the error was 'Unable to bind to the destination server in DNS'. After lots of false starts I got to Xtra DNS... protocol)
Set q=mx Server 202.27.184.3
I tried that and got much strangeness when I put in
swiftlink.co.nz
I should have gotten...
Server: alien.xtra.co.nz Address: 202.27.184.3
Non-authoritative answer: swiftlink.co.nz MX preference = 10, mail exchanger = mail.swiftlink.co.nz
swiftlink.co.nz nameserver = dns1.clear.net.nz swiftlink.co.nz nameserver = dns2.clear.net.nz mail.swiftlink.co.nz internet address = 203.167.202.72 dns1.clear.net.nz internet address = 203.97.33.1 dns2.clear.net.nz internet address = 203.97.37.1
And in fact, I often do, but I also get...
Server: alien.xtra.co.nz Address: 202.27.184.3
Non-authoritative answer:
That's right, end of report - I have received stranger though - how about this???

(Blank lines removed for readability - sorry if they were important) I have reproduced these results from 3 different Internet connections, 2 Jetstreams (Both with Xtra) and a Jetstart with Attica. Same results at all 3 places... Oh, if I type
server 203.97.33.14
It all works perfectly... I rang Xtra and did speak to someone that sounded as if they knew what they were talking about, and even emailed copies of the above logs, and they claimed that nothing was wrong. Have I missed something blindingly obvious? Also, omitting 'set vc' to leave it on UDP makes alien.xtra.co.nz play nice again. Late discovery - 202.27.184.5 seems ok - this makes me suspect Xtra has problems even more, but my problems have been manifest over the last 3-4 days and they have denied any problems.
