Unable to send and receive email

Hello
Good day All,

We’re having a problem in send/receive email. Below image was the problem shown on MXTOOL.COM

Hi and welcome!

iriso.com.ph does not seem to exist.

iriso.com exists, so does iriso.ph, just not iriso.com.ph

Hello! Thank you for your reply

We’ve been using the iriso.com.ph for several years. It just happened last month that we we’re not able to send and receive.

I suggest you provide more details on what exactly you are trying to do. Originating domain and which destination domain and who/where they are hosted.

In any case, iriso,com.ph does not resolve e.g. public internet DNS is not aware of such a domain. Is it perhaps an internal domain, not reachable from the internet?

Hi

Whois.com confirms that the domain “iriso.com.ph” does NOT exist (or is no more valid) !!!

No mail sending or recieving will work (except maybe internally / locally).

Maybe the domain has been lost (unpaid for…)?

Check your domain hoster / provider.

My 2 cents
Andy

Thank you so much for your reply.

Our domain was registered undet dot.ph
I tried the MXTOOLBOX.COM DNS lookup and it shows that iriso.com.ph that DNS Record not found.

Correct, the domain does not exist, hence you can not send /receive mail from/to that domain.
