Can someone provide me with some information on a delivery failure issue that started Monday? Our system is setup so a Linux machine running Redhat AS 3 update 8 serves as an external DNS and external email gateway. It receives all incoming emails using qmail toaster 1.2 smtp server. Qmail then delivers the emails to a separate server running Windows Exchange 2000 that houses the mailboxes. On Monday sometime around noon my qmail stopped delivering mail to mailboxes on the Exchange 2000 server. Below is the rejection notice that was being returned to senders:
Hi. This is the qmail-send program at dellapp02.occa.state.ok.us.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<[EMAIL PROTECTED]>:
Sorry. Although I'm listed as a best-preference MX or A for that host,
it isn't in my control/locals file, so I don't treat it as local. (#5.4.6)
