Gmail Kisses "On Behalf Of" Goodbye, Enables Support For Third-Party Outbound Servers
If the previous paragraph confused you, here’s an explanation: Many people like to use Gmail’s web interface for their Email but don’t have the option of using Google Apps on their mail server, especially when it’s for their work account. Fortunately there’s a work around to this: simply have your work Email account auto-forward all incoming messages to your Gmail account. The option even allows you to send messages and make them look like they’re coming from your work account, rather than you Gmail account, but with one caveat: rather than actually send these messages from your work address, Google includes a message that says the message was sent “On Behalf Of” your address, while still showing the name of the Gmail account it was actually sent from.
It’s true that most people never noticed this (in fact many mail clients don’t show the “On Behalf Of” at all under default settings), and even if they did see it they probably didn’t care in the slightest. But it’s still been a source of annoyance for many of us.
