When I write a mail in Mail.app (using MacOS X Mavericks 10.9.2 here), I have this "From" Drop down menu which allows me to select from which of my accounts I want to send that mail.
In my case, this drop-down menu has 33 items.
How is this menu configured?
I ask because it is tied to the account list, but not quite the same. My account list has only 17 items for example.
I have a few forward email addresses that show up there, but not all.
At this moment, I would like to have one of my email sent with a "From" header that is a forward email address that doesn't show up in that menu.
