I have also had issues like this and I cannot find anyone else on the forum bar this thread who has the same trouble like this one:

anyname@hotmail.com
SMTP error from remote mail server after MAIL FROM:<postmaster@mispl.com> SIZE=1735:
host mx4.hotmail.com [65.54.244.104]: 550 Command rejected for policy reasons. For troubleshooting information, go to http://postmaster.msn.com

Many Thanks

 

Did you follow the instructions and visit postmaster.msn.com to troubleshoot the problem?

 

I have finally got a reply from Hotmail and got the following responce,

So im now e-mailing symantec to get myself unblocked!

 

Use SPF records

One of the suggestions @ the referenced hotmail site is to use SPF records. More and more groups are relying on them.

There's a pretty good wizard at http://old.openspf.org/wizard.html that walks you through setting up the properly formatted text record for your DNS. Even with this wizard, though, it can be confusing. Read carefully. If you're on a VPS, you should probably include the hostname of the sending server as well as the domain of the user.

The more SPF is used, the less attractive special Domain keys being pushed by Yahoo become (see http://www.ahfx.net/weblog.php?article=107).

(SPF == Sender Policy Framework and gives receiving SMTP servers a method of confirming that the sending server is not sending spoofed junk mail by a simple verification method).

 

Of course, Hotmail is not complying with the SPF framework... they are rejecting outright mail from domains that do not have an SPF record
