Client of mine called this morning saying they are having issues sending out mail. I log into one of the workstations and saw "delivery to the following recipients has been delayed"
I log into the server (SBS2003) with a bunch of Small Business SMTP Connectors just sitting in the queue.
If I do a nslookup of the domain it resolves the MX Records. I went to Default SMTP Virtual Server and added the ISP DNS servers under Advanced. Didn't fix anything.
If I right click on Small Business SMTP Connector and send mail out through Smart Host (using mail.optonline.net which is our ISP mail server) and not through Direct Send it works.
But I have alot of my clients using Direct Send and it all works fine. So any idea on what I can do?
