imap.folder:: The folder to drop the mails into, which is typically the Drafts folder. For example: "INBOX.Drafts", "INBOX/Drafts" or "[Gmail]/Drafts". Required. imap.tunnel:: Command used to set up a tunnel to the IMAP server through which commands will be piped instead of using a direct network connection to the server. Required when imap.host is not set. imap.host:: A URL identifying the server. Use an `imap://` prefix for non-secure connections and an `imaps://` prefix for secure connections. Ignored when imap.tunnel is set, but required otherwise. imap.user:: The username to use when logging in to the server. imap.pass:: The password to use when logging in to the server. imap.port:: An integer port number to connect to on the server. Defaults to 143 for imap:// hosts and 993 for imaps:// hosts. Ignored when imap.tunnel is set. imap.sslverify:: A boolean to enable/disable verification of the server certificate used by the SSL/TLS connection. Default is `true`. Ignored when imap.tunnel is set. imap.preformattedHTML:: A boolean to enable/disable the use of html encoding when sending a patch. An html encoded patch will be bracketed with
	and have a content type of text/html.  Ironically, enabling this
	option causes Thunderbird to send the patch as a plain/text,
	format=fixed email.  Default is `false`.

imap.authMethod::
	Specify the authentication method for authenticating with the IMAP server.
	If Git was built with the NO_CURL option, or if your curl version is older
	than 7.34.0, or if you're running git-imap-send with the `--no-curl`
	option, the only supported method is 'CRAM-MD5'. If this is not set
	then 'git imap-send' uses the basic IMAP plaintext LOGIN command.
