Decommissioned the last EX 5.5 Server this past weekend. Getting mail coming in from the Internet doesn't look like mail is getting of the smtp-server (messages are being queued - remote delivery) message I'm getting when I look at the queued messages is "Unable to bind to the destination server in DNS. In EX5.5 - the IMS Connector was forwarding mail thru an ISP - setup the smtp server with a smarthost. Read articles on this site besides smarthost and external dns servers on the smtp virtual server I have gone back and setup my dns server as a forwarder - checked it from the ex2000 server with nslookup everything looked good - setup protocol rules for SMTP and DNS and created a smtp server publishing rule according to ISA Server SMTP Server Support article - IIS is running on the same server as EX2000 and on no other server at this time. Does anybody have any ideas what's going on - I could really use some help.
