Exchange 2010 - We're not getting all our email.. Where to look?

[jmair]

Sorry for the vague subject line, but I haven't been able to identify anything that shows why we aren't getting all of our email.

 

I have a PDC and a BDC. Our email subdomain is mail.parkcountyre2.org and nslookup looks like it points to our server just fine. NAT is configured correctly or no email would make it to us.

 

I did however change our ssl certificate last week, but even if I send an email who is offsite, when they reply they get a bounce back. But I am getting emails from other locations just fine.

 

Any ideas on where to look are most welcome.

 

Thanks guys.

There is an inconsistency in DNS somwhere I think.

 

Seen two different IP's returned for your mail server MX.

edline hosts our website somewhere. but mail.parkcountyre2.org should go directly to my server at 64.25.235.35...

Thanks Rob, that's what I needed to know!

((having a pair of eyes off site is great.. thanks!))

Getting more consistent results now.

 

And Telnet to your server ok.
