git-send-email \- Send a collection of patches as emails
.SH "SYNOPSIS"
.sp
.nf
\fIgit send\-email\fR [<options>] (<file>|<directory>)\&...\:
\fIgit send\-email\fR [<options>] <format\-patch\-options>
\fIgit send\-email\fR \-\-dump\-aliases
\fIgit send\-email\fR \-\-translate\-aliases
.fi
.SH "DESCRIPTION"
.sp
Takes the patches given on the command line and emails them out\&. Patches can be specified as files, directories (which will send all files in the directory), or directly as a revision list\&. In the last case, any format accepted by \fBgit-format-patch\fR(1) can be passed to \fBgit\fR \fBsend\-email\fR, as well as options understood by \fBgit-format-patch\fR(1)\&.
.sp
The header of the email is configurable via command\-line options\&. If not specified on the command line, the user will be prompted with a ReadLine enabled interface to provide the necessary information\&.
.sp
There are two formats accepted for patch files:
.sp
.RS 4
.ie n \{\
\h'-04' 1.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  1." 4.2
.\}
mbox format files
.sp
This is what
\fBgit-format-patch\fR(1)
generates\&. Most headers and MIME formatting are ignored\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04' 2.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  2." 4.2
.\}
The original format used by Greg Kroah\-Hartman\(cqs
\fBsend_lots_of_email\&.pl\fR
script
.sp
This format expects the first line of the file to contain the
\fBCc:\fR
value and the
\fBSubject:\fR
of the message as the second line\&.
.RE
.SH "OPTIONS"
.SS "Composing"
.PP
\-\-annotate
.RS 4
Review and edit each patch you\(cqre about to send\&. Default is the value of
\fBsendemail\&.annotate\fR\&. See the CONFIGURATION section for
\fBsendemail\&.multiEdit\fR\&.
.RE
.PP
\-\-bcc=<address>,\&...\:
.RS 4
Specify a
\fBBcc:\fR
value for each email\&. Default is the value of
\fBsendemail\&.bcc\fR\&.
.sp
This option may be specified multiple times\&.
.RE
.PP
\-\-cc=<address>,\&...\:
.RS 4
Specify a starting
\fBCc:\fR
value for each email\&. Default is the value of
\fBsendemail\&.cc\fR\&.
.sp
This option may be specified multiple times\&.
.RE
.PP
\-\-compose
.RS 4
Invoke a text editor (see GIT_EDITOR in
\fBgit-var\fR(1)) to edit an introductory message for the patch series\&.
.sp
When
\fB\-\-compose\fR
is used,
\fBgit\fR
\fBsend\-email\fR
will use the
\fBFrom\fR,
\fBTo\fR,
\fBCc\fR,
\fBBcc\fR,
\fBSubject\fR,
\fBReply\-To\fR, and
\fBIn\-Reply\-To\fR
headers specified in the message\&. If the body of the message (what you type after the headers and a blank line) only contains blank (or
\fBGit:\fR
prefixed) lines, the summary won\(cqt be sent, but the headers mentioned above will be used unless they are removed\&.
.sp
Missing
\fBFrom\fR
or
\fBIn\-Reply\-To\fR
headers will be prompted for\&.
.sp
See the CONFIGURATION section for
\fBsendemail\&.multiEdit\fR\&.
.RE
.PP
\-\-from=<address>
.RS 4
Specify the sender of the emails\&. If not specified on the command line, the value of the
\fBsendemail\&.from\fR
configuration option is used\&. If neither the command\-line option nor
\fBsendemail\&.from\fR
are set, then the user will be prompted for the value\&. The default for the prompt will be the value of
\fBGIT_AUTHOR_IDENT\fR, or
\fBGIT_COMMITTER_IDENT\fR
if that is not set, as returned by
\fBgit\fR
\fBvar\fR
\fB\-l\fR\&.
.RE
.PP
\-\-reply\-to=<address>
.RS 4
Specify the address where replies from recipients should go to\&. Use this if replies to messages should go to another address than what is specified with the
\fB\-\-from\fR
parameter\&.
.RE
.PP
\-\-in\-reply\-to=<identifier>
.RS 4
Make the first mail (or all the mails with
\fB\-\-no\-thread\fR) appear as a reply to the given Message\-ID, which avoids breaking threads to provide a new patch series\&. The second and subsequent emails will be sent as replies according to the
\fB\-\-\fR[\fBno\-\fR]\fBchain\-reply\-to\fR
setting\&.
.sp
So for example when
\fB\-\-thread\fR
and
\fB\-\-no\-chain\-reply\-to\fR
are specified, the second and subsequent patches will be replies to the first one like in the illustration below where [\fBPATCH\fR
\fBv2\fR
\fB0/3\fR] is in reply to [\fBPATCH\fR
\fB0/2\fR]:
.sp
.if n \{\
.RS 4
.\}
.nf
[PATCH 0/2] Here is what I did\&.\&.\&.
  [PATCH 1/2] Clean up and tests
  [PATCH 2/2] Implementation
  [PATCH v2 0/3] Here is a reroll
    [PATCH v2 1/3] Clean up
    [PATCH v2 2/3] New tests
    [PATCH v2 3/3] Implementation
.fi
.if n \{\
.RE
.\}
.sp
Only necessary if
\fB\-\-compose\fR
is also set\&. If
\fB\-\-compose\fR
is not set, this will be prompted for\&.
.RE
.PP
\-\-outlook\-id\-fix, \-\-no\-outlook\-id\-fix
.RS 4
Microsoft Outlook SMTP servers discard the Message\-ID sent via email and assign a new random Message\-ID, thus breaking threads\&.
.sp
With
\fB\-\-outlook\-id\-fix\fR,
\fBgit\fR
\fBsend\-email\fR
uses a mechanism specific to Outlook servers to learn the Message\-ID the server assigned to fix the threading\&. Use it only when you know that the server reports the rewritten Message\-ID the same way as Outlook servers do\&.
.sp
Without this option specified, the fix is done by default when talking to
\fIsmtp\&.office365\&.com\fR
or
\fIsmtp\-mail\&.outlook\&.com\fR\&. Use
\fB\-\-no\-outlook\-id\-fix\fR
to disable even when talking to these two servers\&.
.RE
.PP
\-\-subject=<string>
.RS 4
Specify the initial subject of the email thread\&. Only necessary if
\fB\-\-compose\fR
is also set\&. If
\fB\-\-compose\fR
is not set, this will be prompted for\&.
.RE
.PP
\-\-to=<address>,\&...\:
.RS 4
Specify the primary recipient of the emails generated\&. Generally, this will be the upstream maintainer of the project involved\&. Default is the value of the
\fBsendemail\&.to\fR
configuration value; if that is unspecified, and
\fB\-\-to\-cmd\fR
is not specified, this will be prompted for\&.
.sp
This option may be specified multiple times\&.
.RE
.PP
\-\-8bit\-encoding=<encoding>
.RS 4
When encountering a non\-ASCII message or subject that does not declare its encoding, add headers/quoting to indicate it is encoded in <encoding>\&. Default is the value of the
\fBsendemail\&.assume8bitEncoding\fR; if that is unspecified, this will be prompted for if any non\-ASCII files are encountered\&.
.sp
Note that no attempts whatsoever are made to validate the encoding\&.
.RE
.PP
\-\-compose\-encoding=<encoding>
.RS 4
Specify encoding of compose message\&. Default is the value of the
\fBsendemail\&.composeEncoding\fR; if that is unspecified, UTF\-8 is assumed\&.
.RE
.PP
\-\-transfer\-encoding=(7bit|8bit|quoted\-printable|base64|auto)
.RS 4
Specify the transfer encoding to be used to send the message over SMTP\&.
\fB7bit\fR
will fail upon encountering a non\-ASCII message\&.
\fBquoted\-printable\fR
can be useful when the repository contains files that contain carriage returns, but makes the raw patch email file (as saved from an MUA) much harder to inspect manually\&.
\fBbase64\fR
is even more fool proof, but also even more opaque\&.
\fBauto\fR
will use
\fB8bit\fR
when possible, and
\fBquoted\-printable\fR
otherwise\&.
.sp
Default is the value of the
\fBsendemail\&.transferEncoding\fR
configuration value; if that is unspecified, default to
\fBauto\fR\&.
.RE
.PP
\-\-xmailer, \-\-no\-xmailer
.RS 4
Add (or prevent adding) the
\fBX\-Mailer:\fR
header\&. By default, the header is added, but it can be turned off by setting the
\fBsendemail\&.xmailer\fR
configuration variable to
\fBfalse\fR\&.
.RE
.SS "Sending"
.PP
\-\-envelope\-sender=<address>
.RS 4
Specify the envelope sender used to send the emails\&. This is useful if your default address is not the address that is subscribed to a list\&. In order to use the
\fBFrom\fR
address, set the value to
\fBauto\fR\&. If you use the
\fBsendmail\fR
binary, you must have suitable privileges for the
\fB\-f\fR
parameter\&. Default is the value of the
\fBsendemail\&.envelopeSender\fR
configuration variable; if that is unspecified, choosing the envelope sender is left to your MTA\&.
.RE
.PP
\-\-sendmail\-cmd=<command>
.RS 4
Specify a command to run to send the email\&. The command should be sendmail\-like; specifically, it must support the
\fB\-i\fR
option\&. The command will be executed in the shell if necessary\&. Default is the value of
\fBsendemail\&.sendmailCmd\fR\&. If unspecified, and if
\fB\-\-smtp\-server\fR
is also unspecified,
\fBgit\fR
\fBsend\-email\fR
will search for
\fBsendmail\fR
in
\fB/usr/sbin\fR,
\fB/usr/lib\fR
and
\fB$PATH\fR\&.
.RE
.PP
\-\-smtp\-encryption=<encryption>
.RS 4
Specify in what way encrypting begins for the SMTP connection\&. Valid values are
\fBssl\fR
and
\fBtls\fR\&. Any other value reverts to plain (unencrypted) SMTP, which defaults to port 25\&. Despite the names, both values will use the same newer version of TLS, but for historic reasons have these names\&.
\fBssl\fR
refers to "implicit" encryption (sometimes called SMTPS), that uses port 465 by default\&.
\fBtls\fR
refers to "explicit" encryption (often known as STARTTLS), that uses port 25 by default\&. Other ports might be used by the SMTP server, which are not the default\&. Commonly found alternative port for
\fBtls\fR
and unencrypted is 587\&. You need to check your provider\(cqs documentation or your server configuration to make sure for your own case\&. Default is the value of
\fBsendemail\&.smtpEncryption\fR\&.
.RE
.PP
\-\-smtp\-domain=<FQDN>
.RS 4
Specifies the Fully Qualified Domain Name (FQDN) used in the HELO/EHLO command to the SMTP server\&. Some servers require the FQDN to match your IP address\&. If not set,
\fBgit\fR
\fBsend\-email\fR
attempts to determine your FQDN automatically\&. Default is the value of
\fBsendemail\&.smtpDomain\fR\&.
.RE
.PP
\-\-smtp\-auth=<mechanisms>
.RS 4
Whitespace\-separated list of allowed SMTP\-AUTH mechanisms\&. This setting forces using only the listed mechanisms\&. Example:
.sp
.if n \{\
.RS 4
.\}
.nf
$ git send\-email \-\-smtp\-auth="PLAIN LOGIN GSSAPI" \&.\&.\&.
.fi
.if n \{\
.RE
.\}
.sp
If at least one of the specified mechanisms matches the ones advertised by the SMTP server and if it is supported by the utilized SASL library, the mechanism is used for authentication\&. If neither
\fBsendemail\&.smtpAuth\fR
nor
\fB\-\-smtp\-auth\fR
is specified, all mechanisms supported by the SASL library can be used\&. The special value
\fBnone\fR
maybe specified to completely disable authentication independently of
\fB\-\-smtp\-user\fR\&.
.RE
.PP
\-\-smtp\-pass[=<password>]
.RS 4
Password for SMTP\-AUTH\&. The argument is optional: If no argument is specified, then the empty string is used as the password\&. Default is the value of
\fBsendemail\&.smtpPass\fR, however
\fB\-\-smtp\-pass\fR
always overrides this value\&.
.sp
Furthermore, passwords need not be specified in configuration files or on the command line\&. If a username has been specified (with
\fB\-\-smtp\-user\fR
or a
\fBsendemail\&.smtpUser\fR), but no password has been specified (with
\fB\-\-smtp\-pass\fR
or
\fBsendemail\&.smtpPass\fR), then a password is obtained using
\fBgit-credential\fR(1)\&.
.RE
.PP
\-\-no\-smtp\-auth
.RS 4
Disable SMTP authentication\&. Short hand for
\fB\-\-smtp\-auth=none\fR\&.
.RE
.PP
\-\-smtp\-server=<host>
.RS 4
If set, specifies the outgoing SMTP server to use (e\&.g\&.
\fBsmtp\&.example\&.com\fR
or a raw IP address)\&. If unspecified, and if
\fB\-\-sendmail\-cmd\fR
is also unspecified, the default is to search for
\fBsendmail\fR
in
\fB/usr/sbin\fR,
\fB/usr/lib\fR
and
\fB$PATH\fR
if such a program is available, falling back to
\fBlocalhost\fR
otherwise\&.
.sp
For backward compatibility, this option can also specify a full pathname of a sendmail\-like program instead; the program must support the
\fB\-i\fR
option\&. This method does not support passing arguments or using plain command names\&. For those use cases, consider using
\fB\-\-sendmail\-cmd\fR
instead\&.
.RE
.PP
\-\-smtp\-server\-port=<port>
.RS 4
Specifies a port different from the default port (SMTP servers typically listen to smtp port 25, but may also listen to submission port 587, or the common SSL smtp port 465); symbolic port names (e\&.g\&.
\fBsubmission\fR
instead of 587) are also accepted\&. The port can also be set with the
\fBsendemail\&.smtpServerPort\fR
configuration variable\&.
.RE
.PP
\-\-smtp\-server\-option=<option>
.RS 4
If set, specifies the outgoing SMTP server option to use\&. Default value can be specified by the
\fBsendemail\&.smtpServerOption\fR
configuration option\&.
.sp
The
\fB\-\-smtp\-server\-option\fR
option must be repeated for each option you want to pass to the server\&. Likewise, different lines in the configuration files must be used for each option\&.
.RE
.PP
\-\-smtp\-ssl
.RS 4
Legacy alias for
\fB\-\-smtp\-encryption\fR
\fBssl\fR\&.
.RE
.PP
\-\-smtp\-ssl\-cert\-path
.RS 4
Path to a store of trusted CA certificates for SMTP SSL/TLS certificate validation (either a directory that has been processed by
\fBc_rehash\fR, or a single file containing one or more PEM format certificates concatenated together: see the description of the
\fB\-CAfile\fR
\fI<file>\fR
and the
\fB\-CApath\fR
\fI<dir>\fR
options of
\m[blue]\fBhttps://docs\&.openssl\&.org/master/man1/openssl\-verify/\fR\m[]
[OpenSSL\(cqs verify(1) manual page] for more information on these)\&. Set it to an empty string to disable certificate verification\&. Defaults to the value of the
\fBsendemail\&.smtpSSLCertPath\fR
configuration variable, if set, or the backing SSL library\(cqs compiled\-in default otherwise (which should be the best choice on most platforms)\&.
.RE
.PP
\-\-smtp\-user=<user>
.RS 4
Username for SMTP\-AUTH\&. Default is the value of
\fBsendemail\&.smtpUser\fR; if a username is not specified (with
\fB\-\-smtp\-user\fR
or
\fBsendemail\&.smtpUser\fR), then authentication is not attempted\&.
.RE
.PP
\-\-smtp\-debug=(0|1)
.RS 4
Enable (1) or disable (0) debug output\&. If enabled, SMTP commands and replies will be printed\&. Useful to debug TLS connection and authentication problems\&.
.RE
.PP
\-\-imap\-sent\-folder=<folder>
.RS 4
Some email providers (e\&.g\&. iCloud) do not send a copy of the emails sent using SMTP to the
\fBSent\fR
folder or similar in your mailbox\&. Use this option to use
\fBgit\fR
\fBimap\-send\fR
to send a copy of the emails to the folder specified using this option\&. You can run
\fBgit\fR
\fBimap\-send\fR
\fB\-\-list\fR
to get a list of valid folder names, including the correct name of the
\fBSent\fR
folder in your mailbox\&. You can also use this option to send emails to a dedicated IMAP folder of your choice\&.
.sp
This feature requires setting up
\fBgit\fR
\fBimap\-send\fR\&. See
\fBgit-imap-send\fR(1)
for instructions\&.
.RE
.PP
\-\-use\-imap\-only, \-\-no\-use\-imap\-only
.RS 4
If this is set, all emails will only be copied to the IMAP folder specified with
\fB\-\-imap\-sent\-folder\fR
or
\fBsendemail\&.imapSentFolder\fR
and will not be sent to the recipients\&. Useful if you just want to create a draft of the emails and use another email client to send them\&. If disabled with
\fB\-\-no\-use\-imap\-only\fR, the emails will be sent like usual\&. Disabled by default, but the
\fBsendemail\&.useImapOnly\fR
configuration variable can be used to enable it\&.

.RS 4
Some email servers (e\&.g\&.
\fIsmtp\&.163\&.com\fR) limit the number of emails to be sent per session (connection) and this will lead to a failure when sending many messages\&. With this option, send\-email will disconnect after sending
\fI<num>\fR
messages and wait for a few seconds (see
\fB\-\-relogin\-delay\fR) and reconnect, to work around such a limit\&. You may want to use some form of credential helper to avoid having to retype your password every time this happens\&. Defaults to the
\fBsendemail\&.smtpBatchSize\fR
configuration variable\&.
.RE
.PP
\-\-relogin\-delay=<int>
