Thanks for that info. Can someone also comment on this? I asked a friend via email and this was his response to the same issue:
****************************** "I used nslookup to verify the address your queue is showing, and it does correspond to je.jfcom.mil. But a request for the mail-exchangers for jfcom.mil does not indicate that this host should be receiving mail. The mail-exchangers for that domain are: smtp01.jfcom.mil smtp02.jfcom.mil So this problem resolves into a new one: how did your Postfix come up with the name je.jfcom.mil to send messages to? Did the user explicitly specify that host as a target? Or did Postfix get bad info from its DNS lookup of MX records? Or did something else happen to misdirect these messages? Only a good look at the mail headers for the offending messages will tell you that. When a message finally expires and is sent back to its originator (or to the postmaster), you will need to examine the headers to see at what stage of forwarding a host made the choice to use the wrong mail exchanger. Then further work will be needed to figure out why." ****************************** My question is how did he find smtp01.jfcom.mil? And more important, why then is my Postfix server trying to send to a different smtp address?
