Weirdest DNS problem I've seen

[David Lau]

Hello,

I have a domain with DNS hosting at ZE and it's running email via Google Apps for Business (Gmail backend).

For a few weeks I and my users have been missing mail but I've narrowed it down to this:

New emails (new thread) come through to my domain without any problems BUT replies do not come in! Obviously, I have checked and the "reply to email" is 100% correct.

The NS in the domain record and registrar and root registry all match up (dns1 and dns2.zoneedit.com). I've thrown all I can think of at this problem and have only just discovered that when I query dns1.zoneedit.com for my domains MX records, it spits out different info AND also it thinks that the Gmail servers are running internally at ZoneEdit! This is a major problem if I am interpreting this correctly.

My domain is gatepost.com and here are the results of a query directed to dns1.zoneedit.com, note the 192 emails that come up for google.com servers. Specifically: "alt1.aspmx.l.google.com. 3600 IN A 192.64.147.142"

alt1.aspmx.l.google.com is actually 74.125.201.26 not 192.64.147.142 The same follows suit for all the other altX.aspmx.l.google.com addresses!

"MX" DNS records for gatepost.com using dns1.zoneedit.com: gatepost.com. 3600 IN MX 1 aspmx.l.google.com. gatepost.com. 3600 IN MX 5 alt1.aspmx.l.google.com. gatepost.com. 3600 IN MX 5 alt2.aspmx.l.google.com. gatepost.com. 3600 IN MX 10 alt4.aspmx.l.google.com. gatepost.com. 3600 IN MX 10 alt3.aspmx.l.google.com. <br />
Additional records:
aspmx.l.google.com. 3600 IN A 192.64.147.142 alt1.aspmx.l.google.com. 3600 IN A 192.64.147.142 alt2.aspmx.l.google.com. 3600 IN A 192.64.147.142 alt3.aspmx.l.google.com. 3600 IN A 192.64.147.142 alt4.aspmx.l.google.com. 3600 IN A 192.64.147.142 dns1.zoneedit.com. 300 IN A 31.220.0.12 dns1.zoneedit.com. 300 IN AAAA 2a00:1ca8:2c::1:1686 dns2.zoneedit.com. 300 IN A 166.88.18.58 dns2.zoneedit.com. 300 IN AAAA 2607:f358:1:ffc0::11

Is this the cause of the strangest email/dns issues I've encountered?

ps. Query tool used is: at manytools.org/network/query-dns-records-online/go

Thx,
