How to send mail from Gmail on behalf of another account on OS X?

Question

gmail

There is a gmail account to which some other accounts are connected, that is, by going to Google mail, you can send a letter not only from the main account, but also connected ones. This method works on the web and in the native gmail mobile client for both Android and iOS. I would like to pick up an application for OS X that would also be so skillful, since using the web version is not always convenient.
I tried to achieve this in my native mail.app client, but as I understand it, the IMAP protocol does not know how. Of course, you can register separately each of the additional email accounts in mail.app, but then the letters sent through the additional account will not be centrally stored in the Google mailbox, which is unacceptable. Maybe there is something like a native client from Google for OS X.

Answer 1

It is necessary to try to register additional smtp accounts in Mail.app, instead of full-fledged accounts; plus uncheck "Only use this server to send mail".
