I have an Exchange Server 2007 that has suddenly stopped receiving mail, been working fine for 2 years now.  The mail is queued up at the external webmail sites waiting to flow down.  Sending out appears to be fine.  Please advise on troubleshooting steps.  Thanks in Advance

You may be suffering from Backpressure and I have a quick fix for that in my article:

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_4259-Exchange-2007-2010-Backpressure-Quick-Fix.html

Essentially, you are probably low in disk space, so you need to do a tidy up.

Any change made recently, check with your ISP.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

It's not the amount, it's the percentage of free space that's important, that or memory in use.

Is port 25 open happily (you can test on www.canyouseeme.org using port 25)?

Did your MX records change?

Did your domain name need renewing and no-one renewed it?

Port 25 and 587 are happy

Not sure on MX records, can I test somehow?

I have a certificate for the smtp server but I do not necessarily see one for the domain

Yes - check on http://mxtoolbox.com

Did you try my quick fix to see if that resolves the problem?

An expired certificate isn't going to stop you receiving mail.

Could it be DNS at all?

It could be DNS.  Has anything changed lately?

Can you telnet to your server remotely on port 25?

DNS only needs to resolve your IP address of your MX record.

Do you want to divulge your domain name, which I can hide, so I can see if I can spot anything amiss?

Your mx record is not pointing to mail.domain.com, it points to domain.com which is answered by an EXIM box, not Exchange, so I would check your DNS / MX records by the sounds of it.

I use www.dnsstuff.com which tells me what I told you. I have a subscription, but don't think you need one for the domain report.

so is that an issue in the dns records on the server or with the hosting company that sets that mx records?

Your DNS records seem to be managed by gemwebsolutions so it should be them you contact.
