Exchange 2010 Server not sending emails
It worked for a short time, and then for some reason it just stopped. I can't figure out why either. I'm obviously missing something and it's begging to irritate me.
So here is how everything is setup.
The public IP of the server is 99.28.107.226
There is just one server, Windows 2008 R2 with Exchange 2010.
A send connector has been setup to allow all smtp traffic.
I am going to be allowing multple domains to send emails, right now I just have a few setup just to test things out.
The server runs as a domain server, web server, and exchange server.
This system is setup at home, for testing purposes, so that's why there is only one server. I can receive emails just fine.
On my registrar I have DNS setup like this:
A records
www.450p.com 86400 IN A 99.28.107.226
test.450p.com 86400 IN A 99.28.107.226
ftp.450p.com 86400 IN A 99.28.107.226
mail.450p.com 86400 IN A 99.28.107.226
*.450p.com 86400 IN A 99.28.107.226
450p.com 86400 IN A 99.28.107.226
MX Record
450p.com IN MX 10 99.28.107.226
The main domain name of the server in question is ghp.lcl
The user accounts have email accounts setup for 450p.com and 450p.com is an allowed domain in exchange.
On the DNS side of my server I have the following:
(same as parent folder) Start of Authority (SOA) [17], ghp-server.ghp.lcl, hostmaster.ghp.lcl
(same as parent folder) Name Server (NS) ghp-server.ghp.lcl
ftp Host(A) 192.168.1.2
mail Host(A) 192.168.1.2
test Host(A) 192.168.1.2
www Host(A) 192.168.1.2
(same as parent folder) Host (A) 99.28.107.226
The main domain of the server has the DNS records of:
(same as parent folder) Start of Authority (SOA) [35], ghp-server.ghp.lcl, hostmaster.ghp.lcl
(same as parent folder) Name Server (NS) ghp-server.ghp.lcl
(same as parent folder) Host (A) 192.168.1.2
ghp-server Host (A) 192.168.1.2
(same as parent folder) Host (A) 99.28.107.226
Reverse Lookup Zones is setup as:
1.168.192.in-addr.arpa
(same as parent folder) Start of Authority (SOA) [10], ghp-server.ghp.lcl., hostmaster.ghp.lcl.
(same as parrent folder) Name Server (NS) ghp-server.ghp.lcl.
192.168.1.2 Pointer (PTR) mail.450p.com
192.168.1.2 Pointer (PTR) ghp-server.ghp.lcl
I also have another domain out there that I was doing a test with called mail.ghpstudios.com that is also set to 99.28.107.206 (external DNS only). I don't think this would cause any issues, but maybe I'm wrong in that regard.
What I would like is to have the emails that go out say they are from the domain they are being sent from such as 450p.com, not ghp.lcl (which is only an internal domain).
Any ideas what I might be doing wrong here. The only versions of exchange I have worked with before are Exchange 2000, and 2003. 2010 is very different and stumping me on this issue.

Are messages stuck in your outbox or are they bouncing ?

It's configured via dns. The emails leave however I get a message saying the email is being delayed and will continue to retry.
Have you run the Exchange 2010 Best Practices Analyzer from the Toolbox?
If not, please run it and report back any issues.
If not, please run it and report back any issues.
Current issues with your domain:
1. Reverse DNS is NOT setup on your Fixed IP Address (please call SBCGlobal and ask them to set this up accordingly).
2. Your MX record is an IP Address not a Fully Qualified Domain Name
3. Without fixing the MX Record, you may have problems receiving mail
Please correct the above issues to help with your configuration and to help your mail flow both in and out.

I tried something else, which I think shows there maybe a loop or something wrong in DNS externally. I can send emails out just fine apprently, just not to my ghpstudios.com domain.
Here is what I did.
At some point I want the main MX record to be mail.ghpstudios.com and have that point to 99.28.107.226 (it's doing so now). I think I have an A record setup for mail.ghpstudios.com for the IP of 99.28.107.226 (maybe this is the wrong thing??). Then when I setup an MX record I just point it to mail.ghpstudios.com instead of having to type in an IP. Right now the domain 450p.com is setup internally on my Exchange 2010 server, it can receive emails, and it can send out to other domains, except ghpstudios.com.
Any ideas on what I can do to clean this mess up. I must not be seen the logic path of the mail or something right in my head and probably have it just going in circles for all I know.

One other thing, the email address it says it is from is ivan.windon@ghp.lcl (not iwindon@450p.com), I change the send connector to show mail.ghpstudios.com in the specify the FQDN this connector will provide in response to HELO or EHLO. Would that be a reply to address setting I make in the client, or something I need to set on the server.
I see the following for your ghpstudios.com MX records:
Your 2 MX records are:
10 mx1.emailsrvr.com. [TTL=7200] IP=72.4.117.21 (No Glue) [TTL=300] [US]
20 mx2.emailsrvr.com. [TTL=7200] IP=72.4.117.8 (No Glue) [TTL=300] [US]
Where do you think they are pointing to 99.28.107.226?
To setup A and MX records properly, you need to setup an A record called mail and point that to the IP Address, then add an MX record as mail.domain.com and then all will be well.
For example:
Name Type Result
mail A 99.28.107.226
Name Type Priority Result
MX 10 mail.ghpstudios.com
If you have configured ghpstudios.com to be an accepted domain on your server, then the mail will never get sent externally - it will try to send it internally. If you haven't set this up yet, then the mail will be delivered to the existing MX records as I have posted.
The Send Connector FQDN does not have any bearing on the email address domain name. That is down to the Recipient Policy and the account used. Each account will have a default email address (and thus a default email domain). If you want to send out as different domains, you will need a different user account per domain or Outlook configured with a primary Exchange account and separate SMTP / POP3 accounts with the Receive part disabled or your mail will start to loop and your server will clog up.

The ghpstudios.com part is going to be the last thing I move. It's important email that can not be lost, or interupted. Right now I'm doing tests with other domains I own such as 450P.com, I have the following setup for 450p.com now.
Custom A records
*.450p.com 86400 IN A 99.28.107.226
450p.com 86400 IN A 99.28.107.226
mail.450p.com 86400 IN A 99.28.107.226
Add DNS A Record
Built in MX records
Restore default MX records
Custom MX records
450p.com IN MX 10 mail.ghpstudios.com
Add DNS MX Record
Custom CNAME records
Add DNS CNAME Record
Should I change the MX record on the 450P.com DNS setting to say mail.450p.com (it's also registered setup in DNS on the ghpstudios.com domain as mail.ghpstudios.com, all going to the same IP address. What I'm trying to do is move all my domains I own from external sources into my exchange 2010 server and host my email with Exchange and my web sites with IIS7. The IIS7 part seems to be working just fine. Just need to iron out the last few issues on the mail side. Once I have tested that everything is working and ready to go I'll change the A records and MX records on the ghpstudios.com to point to my server (99.28.107.226)
Custom A records
*.450p.com 86400 IN A 99.28.107.226
450p.com 86400 IN A 99.28.107.226
mail.450p.com 86400 IN A 99.28.107.226
Add DNS A Record
Built in MX records
Restore default MX records
Custom MX records
450p.com IN MX 10 mail.ghpstudios.com
Add DNS MX Record

Add DNS CNAME Record
Should I change the MX record on the 450P.com DNS setting to say mail.450p.com (it's also registered setup in DNS on the ghpstudios.com domain as mail.ghpstudios.com, all going to the same IP address.

Okay - so now your MX record for 450p.com is pointing to mail.ghpstudios.com which is technically correct.
Please call your ISP and change the Reverse DNS record on your IP address to mail.ghpstudios.com.
The 450p.com domain can happily have mail.ghpstudios.com as its MX record - the name is fine.

Do I need to bother setting up A records for each of my domains (such as mail.450p.com), or can I just leave them out and point all their MX records to mail.ghpstudios.com.

Ended up having to redo the entire install as there were other issues, and I went the route of Exchange 2007 this time. I set everything up with the A records and MX records and noticed I was still not able to send from a secondary domain to my ghpstudios.com, so since the server looked like it was good to go I switched the MX records on the external DNS and then it started to work as you mentioned. Everything is great now, thanks for the help in sorting this out.
