View Full Version : MX priorities for 2 mail servers

10-26-2006, 10:53 AM
I am trying to resolve "client not being able to recieve emails"
Here is the scoop.
Yesterday, I pointed DNS to wh. Since then client is not able to get mail. client has 2 mail servers. My email to him bounced back wih error message "Connection refused". I have mail servers with priorities 10 and 20 for mail.xxx.com and mail2.xxx.com respectively.

My question is this:
Is this problem stemming from having different priorities?
Can I have same priorities for both? If not, why not.

Thanks for your help

Shouldn't. Have you tried using telnet to connect to the mail servers?

telnet mail.xxx.com 25
A typical conversation goes something like this (your entry in bold)

telnet mail.mydomain.com 25
220 mydomain.com ESMTP Sendmail 8.11.6/8.11.6; Thu, 26 Oct 2006 11:18:07 -0600

Or for the POP3 (receiving) side of things

The other thing to do is to go to http://www.dnsstuff.com and fill out the DNS Lookup for the MX records of your domain in the top right box

Thanks for the detailed info. When I tried telnet it just stayed blank no response at all. I am going to try dns stuff.com next
