Fun with MX Records

Sometime today I was unable to receive mail at the jrpeet.com domain. Earlier I had sent an email to my wife (her home email at jrpeet.com) about some financial transactions I had made and that mail went through. Then this afternoon I sent Kathee a link to a Star Trbune article and that failed. The first image above shows the error (I tried it about 10 times) Here's the text (from my company email account):

Delivery has failed to these recipients or distribution lists:

*******@jrpeet.com

The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator. The following organization rejected your message: m1.dnsix.com.

It's been such a long time since I set up the Google Apps for jrpeet.com that I had nearly completely forgotten how it works.

The second image shows the Google mail settings for jrpeet.com. Note that m1.dnsix.com is listed first.

The next step was to go to Network solutions (my domain registrar) and modify the MX records.

The third image shows the modified MX records. I followed the Google standards (see link below).

It takes a while for the change to propagate across the Internet. So far it is beginning to work. An email sent from my corporate email goes through fine. Email sent from FastMail.FM is not yet going through .

More information on the MX Record is below. Followed by the Google Apps standard

MX record

Excerpt:

A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol.
