You should be able to have your own DNS resolver set up in about 5 minutes.
Then you don't have to worry about such issues.

Subject: Re: [IMail Forum] Strange occasional random issue
Oh what a day from hell...... How do you pick a good DNS server? I had
one from Verio that I've used for the last couple years 161.58.158.113
Ipswitch Techs had me try one of there's while we were testing all the
various problems. Worked well with theirs so I assumed that mine was not
too good... I called Verio where my servers are hosted and they could not
tell me much information about the DNS IP I posted above. They suggested
that because it was a cache DNS server it looks like it may not always be
available and maybe retired soon... Quite frankly I think the Gal knew
less than I did about the server... None the less I tracerouted to the
primary dns servers (ns1 and ns2 .DN.net) and used these in the SMTP area
of iMail 8.21
These worked poorly and allowed my queue to grow to over 100 emails and
stay at that point . Restarting the SMTP server would clear half of them
but then back to the same state... People started calling because there
were errors such as "553 Requested action not taken: Relaying not
permitted" or "553 sorry, that domain isn't in my list of allowed
rcpthosts (#5.7.1)"... I switched back to the IP above and it immediately
cleared the cache and now hovers around 7 or 8 emails pending. Why does
one DNS server IP work better than others? 207.153.206.126 and
161.58.158.45 (bound to ns1 and 2 as mentioned above) failed to perform
worth while.
You would think a company like Verio would have great DNS servers? Am I
missing something? I'm thinking of moving to Rackspace at the end of the
month and hope they can help.

Steve

Ok, so according to this the mail server could not connect to the
primary
rackspace.com mail server.
According to http://dnsreport.com/tools/dnsreport.ch?
domain=rackspace.com,
everything looks good for rackspace.com, so this may have been a
temporary
issue with the rackspace.com mail server, or connectivity between your
server and theirs.
