OK, I'm confused.

I had an email problem with a particularly flaky web host.  Email sent to
any forwarder never arrived with no bounce.  So, I moved the domain name in
question to a new web host and started using eNom's (big domain registrar)
email forwarding.

The odd thing is, we're still having the occasional message completely
disappear, while others take several hours to arrive.  I've also heard
reports of people receiving bounces, but haven't found anyone yet that could
forward me one.  I have many domains using eNom's forwarding service and
this is the only one with a problem.

The only thing I can think of is some big ISP somewhere has cached the DNS
record for the domain and is trying to send mail to the old server.  Other
than that, I am mystified.

Can anyone tell me what their ISP's DNS server shows as an MX record for
pearltrading.ca ?

Thanks

The DNS flip was last week by the way.

Have you seen this?

scroll down ...

ERROR: The IP of one or more of your mail server(s) have no reverse DNS
(PTR) entries (if you see "Timeout" below, it may mean that your DNS
servers did not respond fast enough). RFC1912 2.1 says you should have a
reverse DNS for all your mail servers. It is strongly urged that you have
them, as many mailservers will not accept mail from mailservers with no
reverse DNS entry. You can double-check using the 'Reverse DNS Lookup'
tool at the DNSstuff site (it contacts your servers in real time; the
reverse DNS lookups in the DNS report use our local caching DNS server).
The problem MX records are:
58.188.163.216.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)

WARNING: One or more of your mailservers appears to be an open relay. If
so, this means that you are allowing spammers to freely use the mailserver

and later bounces it, or accepts the relay attempt and then deletes the
E-mail, but this is not common.

Although there's been excellent advice to you earlier in this thread,
I haven't noticed anyone actually answering this question.

eforwardct.name-services.com. [Preference = 5]
eforward1.name-services.com. [Preference = 10]

TTL on each of these is half an hour.

I have not.  Thank you.

These I can't do anything about unfortunately, but I did fix a bunch of
the other errors.  I'll cross my fingers and see what happens.

Thanks again,
HC

Thanks, at least that's as it should be.
