Hi Experts!

Now that I have my exchange server correcting sending and receiving mail from other SMTP domains, I am having another problem.  I have the following MX records:

0     @    exchange.vs-us.com                 TTL 3600
10   @    smtp.secureserver.net               TTL 3600
20   @    mailstore1.secureserver.net      TTL 3600

Some of my user's mail is going to my exchange server, which is priority 0.  The rest is going to the "backup" server hosted by GoDaddy.  I cannot figure out why, and the split seems to be pretty arbitrary.

Any help would be appreciated.

I think you might be having some router problems.  I tried a trace route to your IP - 216.60.35.249 and it started timing out at an SWbell server - 216-60-35-193.ded.swbell.net.  I also tried to Telnet to port 25 on your email server - exchange.vs-us.com - and got no response.

I just found out that the SMTP Virtual Server wasn't running, so I started that and now it works fine.

Along the lines of routing, when I do diagnostics on vs-us.com from mxtoolbox.com, the primary server says that reverse DNS is not configured properly.  Any idea how to fix that?  I'll bet that will cause problems too.

Thanks,

Eric.

It might cause problems with some outgoing messages, since ISP's like AT&T and AOL routinely check the RDNS and reject email that doesn't comply.  The reason you're getting that response is that your reverse DNS record is currently pointing to 216-60-35-249.ded.swbell.net. It should be pointing to your own email host name - exchange.us-vs.com.  You need to go to wherever the external DNS zone is (godaddy, I guess) and remove that PTR record and add on that points to the correct host name.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Reverse DNS is correct... The gateway IP address (216.60.35.194) is what shows when sending through Exchange, and there is a PTR record there for mail.vs-us.com.  We should be in good shape.

I'll post again if I still need more help with the split destinations issue.

Hypercat,

Thanks again.  Everything Kosher... had both IPs on the DNS entry.

Have a great day!
