Hello,
I'm working through an intermittent incoming email bounce problem I
hope
someone can shed some light on. A few major companies are reporting
intermittent bounces when sending email to us.
Someone forwarded a bounce message which contained the following
information:
... connect to mail.greenborder.com [216.52.7.214]: Connection timed
out ...
I do not have a host named 'mail.greenborder.com' in my DNS records.
The IP address is not a mail server, it's an Internap address.

I tried to obtain help through the DNS experts at Network Solutions
through Customer Support; their Customer Support guys are _absolutely
clueless_ on how DNS works. They keep referring me to 'the
provider who
hosts my email service'.
My MX records are here:
http://www.dnsstuff.com/tools/lookup.ch?name=greenborder.com&type=MX
(Temporarily modified for troubleshooting purposes)
greenborder.com. MX IN 7200 USC1.MAILHOSTSXODE.NET. [Preference = 10]
greenborder.com. MX IN 7200 MAILGATE.greenborder.com. [Preference = 1]
greenborder.com. MX IN 7200 USP1.MAILHOSTSXODE.NET. [Preference = 5]
greenborder.com. NS IN 7200 NS31.WORLDNIC.com.
greenborder.com. NS IN 7200 NS32.WORLDNIC.com.
MAILGATE.greenborder.com. A IN 7200 66.123.15.52
Any help would be appreciated.
Your records look fine on my end. Both ns31 and ns32.worldnic.com
return the following MX records:
greenborder.com. 7200 IN MX 5
USP1.MAILHOSTSXODE.NET.
greenborder.com. 7200 IN MX 10
USC1.MAILHOSTSXODE.NET.
greenborder.com. 7200 IN MX 15
MAILGATE.greenborder.com.
You need to find out which resolvers are returning the bad records to
your senders.
HTH.
