MX records. No record for remote.ourdomain.org.uk

Hi,

I have an issue with one server rejecting our emails but I think I should have an additional MX record.

Using MX toolbox. When I search cmp.org.uk I get

10 remote.cmp.org.uk 81.137.89.197 60 min Blacklist Check SMTP Test

When I search remote.cmp.org.uk I get no record exists.

My question is should I have records setup for remote.cmp.org.uk and is so what records do I need.

Thanks.

Randy Poole

What is the email address suffix ex(@domain.com) that the emails are coming from?

cmp.org.uk

The reason I am asking because I ran a test using Wormly and go the following error.

Resolving hostname...

SMTP -> FROM SERVER:

also you may want to set your server up to answer as cmp.org.uk instead of remote.cmp.org.uk

OK is there a way to resolve this. We only have issued with this one server.

Elaborate on (this)

We send emails to other clients / servers from our existing exchange set-up using remote.cmp.org.uk and emails from @cmp.org.uk. We only seems to have issued sending to this one server @curtisfurniture.co.uk

Randy Poole

Gotcha, do you get a NDR or do the emails not go through at all?

David Logan

Hi, no that's the problem we don't get a DNR. Emails are recorded as going out ok. Thats why I used wormly to try figure our whats happening.

Simon Butler (Sembee)

The test you did at Mx Toolbox was correct.
You don't need MX records for remote.cmp.org.uk. The MX records are part of the root domain (cmp.org.uk), of which remote is just a host.

You even have a PTR record in place, so there is no problem there.

Was your test to your own server? If so, it looks like you did things the wrong way round, which is why it has failed (as expected). If you are testing your own server then you put in a local address as the To, not the From, basically the failure is the anti-relaying test.

You need the NDR that is being returned when sending email to the remote host.

Simon.

Hi. I tested from my server remote.cmp.org.uk (@cmp.org.uk) to curtisfurniture.co.uk we can email from Gmail to curtisfurniture.co.uk no problem.

I sent another test to Curtis today and still no NDR back.

Simon Butler (Sembee)

Are the messages in the queue? If you only sent the message today but they are rejecting them in a temporary manner, then the messages will have to timeout (48 hours by default).
