8 # Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
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.

45 --from Specify the "From:" line of the email to be sent.
47 --to Specify the primary "To:" line of the email.
49 --cc Specify an initial "Cc:" list for the entire series
52 --cc-cmd Specify a command to execute per file which adds
53 per file specific cc address entries
55 --bcc Specify a list of email addresses that should be Bcc:
58 --compose Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit
59 an introductory message for the patch series.
61 --subject Specify the initial "Subject:" line.
62 Only necessary if --compose is also set. If --compose
63 is not set, this will be prompted for.
65 --in-reply-to Specify the first "In-Reply-To:" header line.
66 Only used if --compose is also set. If --compose is not
67 set, this will be prompted for.
69 --chain-reply-to If set, the replies will all be to the previous
70 email sent, rather than to the first email sent.
73 --signed-off-cc Automatically add email addresses that appear in
74 Signed-off-by: or Cc: lines to the cc: list. Defaults to on.
76 --smtp-server If set, specifies the outgoing SMTP server to use.
77 Defaults to localhost.
79 --suppress-from Suppress sending emails to yourself if your address
80 appears in a From: line. Defaults to off.
82 --thread Specify that the "In-Reply-To:" header should be set on all
83 emails. Defaults to on.
85 --quiet Make git-send-email less verbose. One line per email
86 should be all that is output.
88 --dry-run Do everything except actually send the emails.
90 --envelope-sender Specify the envelope sender used to send the emails.
