Re: [PATCH v3] send-email: add ability to send a copy of sent emails to an IMAP folder

> Some email providers like Apple iCloud Mail do not support sending a copy
> of sent emails to the "Sent" folder if SMTP server is used. As a
> workaround, various email clients like Thunderbird which rely on SMTP,
> use IMAP to send a copy of sent emails to the "Sent" folder. Something
> similar can be done if sending emails via `git send-email`, by using
> the `git imap-send` command to send a copy of the sent email to an IMAP
> folder specified by the user.
> 
> Add this functionality to `git send-email` by introducing a new
> configuration variable `sendemail.imapfolder` and command line option
> `--imap-folder` which specifies the IMAP folder to send a copy of the
> sent emails to. If specified, a copy of the sent emails will be sent
> by piping the emails to `git imap-send` command, after the all emails are
> sent via SMTP and the SMTP server has been closed.
