10 # Sends a collection of emails to the given email addresses, disturbingly fast.
12 # Supports two formats:
13 # 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)
14 # 2. The original format support by Greg's script:
15 # first line of the message is who to CC,
16 # and second line is the subject of the message.

42 git send-email [options] <file | directory>...
43 Options:
44 --from Specify the "From:" line of the email to be sent.
46 --to Specify the primary "To:" line of the email.
48 --cc Specify an initial "Cc:" list for the entire series
49 of emails.
51 --cc-cmd Specify a command to execute per file which adds
52 per file specific cc address entries
54 --bcc Specify a list of email addresses that should be Bcc:
55 on all the emails.
57 --compose Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit
58 an introductory message for the patch series.
60 --subject Specify the initial "Subject:" line.
61 Only necessary if --compose is also set. If --compose
62 is not set, this will be prompted for.
64 --in-reply-to Specify the first "In-Reply-To:" header line.
65 Only used if --compose is also set. If --compose is not
66 set, this will be prompted for.
68 --chain-reply-to If set, the replies will all be to the previous
69 email sent, rather than to the first email sent.
70 Defaults to on.
72 --signed-off-cc Automatically add email addresses that appear in
73 Signed-off-by: or Cc: lines to the cc: list. Defaults to on.
75 --identity The configuration identity, a subsection to prioritise over
76 the default section.
78 --smtp-server If set, specifies the outgoing SMTP server to use.
79 Defaults to localhost. Port number can be specified here with
80 hostname:port format or by using --smtp-server-port option.
82 --smtp-server-port Specify a port on the outgoing SMTP server to connect to.
84 --smtp-user The username for SMTP-AUTH.
86 --smtp-pass The password for SMTP-AUTH.
88 --smtp-encryption Specify 'tls' for STARTTLS encryption, or 'ssl' for SSL.
89 Any other value disables the feature.
91 --smtp-ssl Synonym for '--smtp-encryption=ssl'. Deprecated.
93 --suppress-cc Suppress the specified category of auto-CC. The category
94 can be one of 'author' for the patch author, 'self' to
95 avoid copying yourself, 'sob' for Signed-off-by lines,
96 'cccmd' for the output of the cccmd, or 'all' to suppress
97 all of these.
99 --suppress-from Suppress sending emails to yourself. Defaults to off.
101 --thread Specify that the "In-Reply-To:" header should be set on all
102 emails. Defaults to on.
104 --quiet Make git-send-email less verbose. One line per email
105 should be all that is output.
107 --dry-run Do everything except actually send the emails.
109 --envelope-sender Specify the envelope sender used to send the emails.
111 --no-validate Don't perform any sanity checks on patches.
