Is it somehow possible to link Facebook address each username is given to Gmail? Obviously, there is the "Accounts, Send mail as" feature, but that used to return an error
... Final-Recipient: rfc822; email@example.com Action: failed Diagnostic-Code: smtp; 550 5.1.1 RCP-P2 http://postmaster.facebook.com/response_codes?ip=126.96.36.199#rcp Refused due to recipient preferences You have requested to add firstname.lastname@example.org to your Gmail account. Confirmation code: XXXXXXXX ...
The XXX part is actually how the email actually reads, the daemon does in fact obfuscate the code prior to sending it back.
I tried again recently, but Facebook mailer does not even return the error message nowadays (alas, it doesn't show in the message center either).
So, how is it possible nowadays?
PS: I can add aliases to gmail. The matter is that Facebook never delivers the verification email.
