can't receive external mail

[alam]

Hello, I installed zimbra on mandriva 2006, and for the most part, it looks like it is working except for one thing. I can send and receive internally. I can send to an external email, but it fails when trying to send from external email to zimbra.

I've searched the forum and wiki, but I could't find anything that helped. Here are some commands I ran that may hopefully help you guys help me out with this.

When I run,

 host `hostname`

I get,

mitch.datacareservices.com has address 10.0.2.6

Then i ran,

dig datacareservices.com mx

and got,

; <<>> DiG 9.3.1 <<>> datacareservices.com mx
;; global options:  printcmd

I'm guessing the problem may have something to do with "mitch.datacareservices.com" and "mail.datacareservices.com." mitch is the test machine while mail is our actual mail server. This is just a guess, as i am pretty new to this.

Any help is appreciated. THanks!

Have a look in the wiki at split domain if you're running both mail servers on your lan.

Also, I noticed that hostname returned 10.0.2.6 and dig returned 10.0.0.24
Which is it ??

10.0.2.6 (mitch.datacareservices.com) is the one i'm trying to test zimbra on. Then when i dig, i get 10.0.0.24, which is the current mail server.

I'm starting to read the wiki for split domain. One thing though; I don't want to accidentally mess up the current mail server.

So far, zimbra looks cool...I just need to get it to receive external emails.

Thanks again for your help.
