What is the content of the message...?
The server doesnt like the domain thruhere.net
which appear in the message and is on a black list...
Try sending a blank email to the same address and confirm that it gets through...

#550-Blacklisted.

This means that they have put you on the blacklisted side.  All emails sent from your domain will be rejected.  Try talking to the email administrator from externalusers.com and ask them to remove you from their blacklisted list.  You then will be able to send emails to anyone in that domain.

Good luck.

thruhere.net is not my domain.

Sender : users@mydomain.com
Recipient : externaluser@externalusers.com

Put your domain in this search and see if you are actually blacklisted...

I am not sure that is actually your domain name that is blocked..

leo.elinuxservers.com #550-Blacklisted URL in message. (thruhere.net) in [ph].

This line means that it found a URL in the message that was blocked in phising category....

Scan your machine for spyware... Do you have someone else in the orgainsation that could send an email to same address from a different computer / user..?

What you mean by " Do you have someone else in the orgainsation that could send an email to same address from a different computer / user.."

Sorry let me explain better.. My idea is that there is a piece of spyware adding stuff to the email that you are sending, the organisation that you are sending to has picked up that in the message there is a URL that is classed in a phising catergory and is therefore blocking the message.

Try sending a message from the user@mydomain.com account to an external email address that you have control over and see if the message is comes out exactly how you sent it...
