Some (external - internally no problem) recipients not receiving email specifically from my account.

I have exchange 2003 (soon to be upgraded). I have Outlook 2007

Im able to send and receive emails to most recipients with out issue.

However there are two recipients that cannot receive my email.

I cannot really find any settings server or client side that might be causing this issue.

Recipients claim that nothing is being filter or blocked on their side and that can receive email from other members in my domain.

Is there anything further I can check on my side to trouble shoot this issue.

Any assistance is appreciated.

Thank you.
