Hi 

Stage 1
A subscriber from a list is not receiving emails I have been posting. I have
check  the mail logs and it show that the emails have been getting through
to that address but not being delivered to the in box. 

Stage 2 
The administrator on the receiving end said is to do with the "reply to
address" that is preventing the email coming through. Meaning the reply to
address must come from a genuine path and not an alias. 

Has anyone come across this before!!

Regards

L Smith
