One of my addresses (it ends with "neverbox") has an exclusive sender from Yahoo.
Whenever I use the reply masked address to reply, the exclusive sender doesn't get the message at all (unless it gets in the spam folder of Yahoo).
But it DOES work if I manually fake my "from" header and send to the real e-mail Yahoo address instead.
Eventually, the destination's name is the same in both cases, so what gives?
Is it because the former option (reply masked address) gets sent to you first and it somehow irritates Yahoo?
