Gmail’s “Accounts” feature lets you send emails from different addresses. I’ve been using it to send emails from my work email address, and emails sent to my work address forward automatically to my Gmail account. That means I can organize, send, and receive all my emails from one central location, without giving away my private email address. Or so I thought.
I just discovered that even when you send email “from” another account, Gmail includes your Gmail account email as the “sender.” The screen-shot of a recent email’s header shows what I mean. Here I sent the email while logged in to my if.website#nosp@m#gmail#h.re#com Gmail account. I sent it as “webmaster#nosp@m#ilfilosofo#h.re#com”, but it says the sender is “if.website#nosp@m#gmail#h.re#com”.
I can’t think of any good reason to make that address public, and worse, nothing in the “Accounts” pages warns you that this will happen.
