Hi Debbie,
Don't know if this has already been said, but I believe that the remote
mail server needs to accept null sender (RFC823?) as a valid address. We
shouldn't need to disable sender verification or change the from address
just because the remote mail server doesn't conform to the RFCs.
The reason for using null sender (correct me if I am wrong) is that this
avoids a loop if they try to perform sender verfication as well.
Cheers
Tim
