I am using Exchange server 2003 with SBS 2003. Open relay is disabled.
My problem is, at exchange server management console, under QUEUE there are many different domain SMTP connectors. All these connectors are at RETRY state. I am trying to delete messages in each queue. I can only delete messages with a SENDER field. The "Delete with no NDR" is disabled.
And also most of those message that show SENDER information are from postmaster@"my domain".
In window explorer, \exchsrvr\mailroot\vs1\queue folder is empty, \exchsrvr\mailroot\vs1\badmail folder is always filled with a lot of mails.
I'v been searching for solution for a while and just couldn't figure our what the problem is. Any help is greatly appreciated!
