Not at all (Len said this, just finding a post to respond to). MS SMTP does not recognize nfsmt.com as a local domain, and it doesn't relay. That MS SMTP server, though it's called prd-web2-nfs-mt.operations.nfsmt.com, will only accept local mail for addresses @prd-web2-nfs-mt.production.nfs.com. This is likely because prd-web2-nfs-mt.production.nfs.com is the Windows host name, and they haven't changed any of the defaults except the SMTP greeting. But the real problem is that your Imail box's DNS isn't returning the MX for nfsfmt.com, which is mail.nfsfmt.com. It's failing over to the A record for nfsfmt.com, which is not a backup MX--though it does have MS SMTP running on port 25--thus it rejects your mail. Fix your DNS settings/server. -Sandy Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
