I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Are you using Exchange?   Two tools to use are:

1.  http://mxtoolbox.com/  (MX Toolbox)  and

2 http://www.intodns.com/  (Into DNS

You may need your ISP to set up the record for you. Make a request to them.

I used mxtoolbox and this is the result : "Loop detected! We were referred back to 'ip address"

And www.intodns.com came back with a whole bunch of information

This was working fine until recently. Does this mean ISP has changed /removed records?

That is a possibility. They should not have without notifying you. But the ISP manages these records, so you should ask them.

By the way internal email works fine and we can send email out to the internet, but not receive email from the internet

I am also waiting on response from registry as the domain expired. But apart from that...is there anything else I am missing
JohnBusiness Consultant (Owner)Commented:
You should get the domain back in order before contacting the ISP. That could be the reason the MX records were removed.
Snowbella KilangitAuthor Commented:
Thank you, I will wait to get the domain back.

Just additional information, the exchange server is in-house not at the ISP...what else do I need to do to confirm, mx records were not removed by another disgruntled admin user?

Thank you in advance
JohnBusiness Consultant (Owner)Commented:
I have serviced in-house Exchange but had to work through the domain supplier to implement the MX records.

Confirm with the domain that you (and only you in IT) and perhaps the business manager are the only people who can change MX or other ISP records (SPF records come to mind).
Snowbella KilangitAuthor Commented:
Ok thank you so I will wait to take back the domain, talk to the isp to see if they removed the mx records.

How about the configuration in the in-house exchange server, how can I check nothing has changed there or on the DNS Server?
JohnBusiness Consultant (Owner)Commented:
The server will look to / see the information kept by the domain. So long as it is set up with proper mail address, it should work.

Once the ISP has put back the records, look at MX Toolbox and Into DNS again to see if anything is missing. Not likely, because (s you said) it was working.

Thank you I will check and post back here

Problem 1

Problem 2
I am also waiting on response from registry as the domain expired. But apart from that...is there anything else I am missing
Domain expiry led to problem 1
Because the domain is expired the registrar can sell it to someone else.. that is a major faux pas. ignoring the emails from the domain registrar is not a good idea.. I hope you are not using godaddy as their fee for expired domains is rather excessive. Always pay for your domain in the longest period that you can afford but I'd suggest at a minimum of 5 years.

Personally for my domains I use cloudlare for my dns for external sites and point the registrar's dns to cloudflare name servers. Since I use multiple registrars it makes management a lot easier.

It won't be long before you won't be able to send mail due to the dns issue with the expired domain

As long as you are quick, you can normally get the domain back. A reputable domain holder will wait (sometimes as long as 30 days). So even though it is not working (which is why we identified way back the reason for the MX record being disabled), you should be able to get your domain back and get working again in short order.

Thank you David and John.

The old incumbent had the renewal reminders sent to his private email. I had no access. I have changed all this. Registrar is waiting on Registry for a response...thats where its at, at the momen

Yes that is what I intend to do now pay for 5 to 10 years.

I will check with the ISP as suggested

I was just wondering if there was something else I needed to check in-house...that may have changed.

All that you have to do is once your domain is back in control to setup the dns records.. Why they have to go to IANA I have no idea they must be a fly-by-night operation I would consider transferring the domain in 60 days

to receive email the sender looks for MX , so if MX is not found no mail wil be delivered.

again us lookup tool to determine if MX exists - go to http://www.dnsstuff.com/

and choose Domainreport - fill in your domain as found on the internet.
