Bcc lost ?

[dvandevate]

How does one see the bcc addresses in an MessageStore.SaveAsync override ?

One can see the values in the IMessageTransaction.To container, but there is no apparent indication here which addresses are To,cc, or ,bcc

The buffer does not contain the bcc.

In an effort to relay the message, one is seemlingly unable to relay the bcc addresses ?

You won't be able to see the BCC or distinguish the CC for that matter, this is all a part of the SMTP protocol design.

So when the mail client sends a message to the mail server, it combines all the address on the TO, CC, and BCC fields and then sends them all together but then doesnt encode the BCC into the actual mail body itself.
