I have a gmail account in Mail.app, example@gmail.com.
How can I send mail from Mail.app using the example+two@gmail.com From address, instead of the example@gmail.com From address?
Looking through all Mail preferences and System Preferences > Internet Accounts I don't see how. Probably there's some workaround though.
This worked for me
Assuming you have already setup the alternate account in your gmail
- Remove the gmail account from your iphone
- Add new mail account
- Settings > Mail > Add Account > Other
- Enter standard gmail id and password in New Account screen
- Enter standard gmail id and password in IMAP and SMTP screens (imap.gmail.com, smtp.gmail.com)
- After account is setup, under "IMAP Account Information" change address field to the desired account (Note that the "Incoming Mail Server" settings will remain as gmail info, this is the difference between creating the account manually and using the automatic gmail setup)
Enjoy
Under Accounts in Preferences, there's a field there called "Email Address:". You can put a comma-separated list of addresses in there, like this:
Now your "Compose" window will have a "From" popup menu that lets you choose your sending address:
AFAIK, this works for pretty much any mail account type, as long as your mail provider allows you to muck around with the From: header.

It's called an email alias.
