+git-imap-send(1)
+================
+
+NAME
+----
+git-imap-send - Send a collection of patches from stdin to an IMAP folder
+
+
+SYNOPSIS
+--------
+[verse]
+'git imap-send' [-v] [-q] [--[no-]curl]
+
+
+DESCRIPTION
+-----------
+This command uploads a mailbox generated with 'git format-patch'
+into an IMAP drafts folder.  This allows patches to be sent as
+other email is when using mail clients that cannot read mailbox
+files directly. The command also works with any general mailbox
+in which emails have the fields "From", "Date", and "Subject" in
+that order.
+
+Typical usage is something like:
+
+git format-patch --signoff --stdout --attach origin | git imap-send
+
+
+OPTIONS
+-------
+
+-v::
+--verbose::
+	Be verbose.
+
+-q::
+--quiet::
+	Be quiet.
+
+--curl::
+	Use libcurl to communicate with the IMAP server, unless tunneling
+	into it.  Ignored if Git was built without the USE_CURL_FOR_IMAP_SEND
+	option set.
+
+--no-curl::
+	Talk to the IMAP server using git's own IMAP routines instead of
+	using libcurl.  Ignored if Git was built with the NO_OPENSSL option
+	set.
+
+
+CONFIGURATION
+-------------
+
+To use the tool, imap.folder and either imap.tunnel or imap.host must be set
+to appropriate values.
+
+Variables

+
+include::config/imap.txt[]
+
+Examples
+~~~~~~~~
+
+Using tunnel mode:
+
+..........................
+[imap]
+    folder = "INBOX.Drafts"
+    tunnel = "ssh -q -C user@example.com /usr/bin/imapd ./Maildir 2> /dev/null"
+..........................
+
+Using direct mode:
+
+.........................
+[imap]
+    folder = "INBOX.Drafts"
+    host = imap://imap.example.com
+    user = bob
+    pass = p4ssw0rd
+.........................
+
+Using direct mode with SSL:
+
+.........................
+[imap]
+    folder = "INBOX.Drafts"
+    host = imaps://imap.example.com
+    user = bob
+    pass = p4ssw0rd
+    port = 123
+    sslverify = false
+.........................
+
+
+EXAMPLES
+--------
+To submit patches using GMail's IMAP interface, first, edit your ~/.gitconfig
+to specify your account settings:
+
+---------
+[imap]
+	folder = "[Gmail]/Drafts"
+	host = imaps://imap.gmail.com
+	user = user@gmail.com
+	port = 993
+	sslverify = false
+---------
+
+You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
+that the "Folder doesn't exist".
+
+Once the commits are ready to be sent, run the following command:
+
+  $ git format-patch --cover-letter -M --stdout origin/master | git imap-send
+
+Just make sure to disable line wrapping in the email client (GMail's web
+interface will wrap lines no matter what, so you need to use a real
+IMAP client).
+
+CAUTION
+-------
+It is still your responsibility to make sure that the email message
+sent by your email program meets the standards of your project.
+Many projects do not like patches to be attached.  Some mail
+agents will transform patches (e.g. wrap lines, send them as
+format=flowed) in ways that make them fail.  You will get angry
+flames ridiculing you if you don't check this.
+
+Thunderbird in particular is known to be problematic.  Thunderbird
+users may wish to visit this web page for more information:
