SECURITY: Two Factor Authentication on Outgoing Messages!
Add feature to have a 2-steps verification on outgoing messages.
Today, my Yahoo forwarded an email BY ITSELF! I don't believe I am hacked as I don't see unusual activity in Security, and I have 2-Factor Authentication login active. But it appears there is nothing to authenticate outgoing messages like my bank authenticates outgoing fund transfers.
Please add 2-Factor Authentication on outgoing messages! I don't know what caused this event, but it is most disconcerting and I have no way to prevent it from recurring. I have some confidential emails that I do not want to be disseminated unscrupulously!
