Emails to Hotmail.com and MSN.com accounts delayed...

I'm running a fresh iinstall of SBS2003 server with Exchange and for some
reason, still unknown, emails to Hotmail.com and MSN.com accounts show up in
the que and eventually kick back a "delayed" email to the sender.

All other domain accounts send out fine with no issues.  Is there a
resolution to this?  Maybe an issue with the ISP or Hosting provider?

What does "domain account" mean in this context? Is this happening only to
one of your users/senders? Or do you mean mail to all other domains is
successfully delivered?

Do you have a dynamic public IP? If so, you should forward your outbound
Internet mail to your ISP's SMTP server as a smarthost (since you're on SBS,
re-run the CEICW to enable that).

If not, does your static public IP have a PTR?

Sorry, the issue happens when any domain users sends an email to any
Hotmail.com or MSN.com account.  The server is behind a firewall connected to
a T1 line.

OK, and what about a PTR? (reverse lookup record)? Look up your domain at
www.dnsreport.com or try

ping -a xxx.xxx.xxx.xxx

(xxx.... being your public IP).

You need a PTR, so if you don't have one, call your ISP (the ones who
provide your T1, not your hosting company) and tell them you need a
PTR/reverse lookup for your public IP.

If you do have one, there are other things to look at.
