Hey Hey,

Could it be that they populated the BCC field and the software/server doesn't translate that into a To field but leaves it in place in the BCC field which is blank to the end-user... that could explain the presence of the BCC: in the headers.

Peace,
HT

[Edit]

Apparently different mail programs or servers (not sure where the translation is done) do deal with emails in different ways..

All of these emails were sent with blank To Fields and only the BCC populated

I also attempted Rogers Yahoo Email but it required I input a To Field...
