Ever since I got E2K over a year ago, I have found that it will not deliver mail to the next highest priority MX record for a given domain if the highest fails.

Here is a perfect example. Fedex.com has 3 MX records;

FedEx.com IN MX 100 mapper.mail.FedEx.com
FedEx.com IN MX 200 smtp.zmd.FedEx.com
FedEx.com IN MX 300 smtp.dmz.FedEx.com

Both the 100 and the 200 refuse connection for whatever reason, (that's not the point). MX record 300 accepts connections.

I replied to an email from a sales rep at FedEx.com yesterday and the message is still sitting in the queue waiting for delivery. It seems to me that E2K querrys the highest priority record, in this case MX 100 mapper.mail.FedEx.com, and if it accepts connections fine but if it doesn't then it won't querry any of the other MX records for delivery.

I have known this to be an issue and have setup a couple of SMTP connectors for a couple of our customers to work around this problem.

I am asking someone with E2K to try and deliver a message to the email address I have for FedEx.com. I know it is good because he emailed me and I replied but the reply is sitting in the queue. If your willing to test delivery, email me at digitalcandy@hotmail.com and I will give you his address. Thanks for your help.

Hi Ryan!

I just emailed your FedEx contact with a cc to you. My server sent the message right away without any fuss and I received an acknowledge message from the FedEx mailing system instantaneously. My Exchange server (I used a SBS2000 installation ű let me know if you want a message from a ôpureö Exchange installation) has the exact same DNS MX records for the fedex.com domain. IĆll forward the receipt as well as the result from the Message Tracking Center to your hotmail account.

Regards,

Johan

Thanks Johan for your help.

I guess my E2K is just weird and won't deliver to the other MX records. [Confused]

Cirwin, I also got your messages too. Your's also delivered successful.

I don't know what the problem can be with my server as I have not had "Stop" errors in the Event Viewer since the initial setup over 1 year ago.

I do know that in any case where the highest priortiy MX fails my server doesn't querry other MX records. Any of you have ideas?

Are you hosting your own DNS?? The reason I ask is because a customer of mine had a similar issue with Fedex and it ended up being stale records in their DNS server. After i had them use an external one (4.2.2.1 is a good one)all mail flowed fine. Just a though [Smile]
