   8# Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
   9#
  10# Sends a collection of emails to the given email addresses, disturbingly fast.
  11#
  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.

  42Options:
  43   --from         Specify the "From:" line of the email to be sent.
  44
  45   --to           Specify the primary "To:" line of the email.
  46
  47   --cc           Specify an initial "Cc:" list for the entire series
  48                  of emails.
  49
  50   --cc-cmd       Specify a command to execute per file which adds
  51                  per file specific cc address entries
  52
  53   --bcc          Specify a list of email addresses that should be Bcc:
  54                  on all the emails.
  55
  56   --compose      Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit
  57                  an introductory message for the patch series.
  58
  59   --subject      Specify the initial "Subject:" line.
  60                  Only necessary if --compose is also set.  If --compose
  61                  is not set, this will be prompted for.
  62
  63   --in-reply-to  Specify the first "In-Reply-To:" header line.
  64                  Only used if --compose is also set.  If --compose is not
  65                  set, this will be prompted for.
  66
  67   --chain-reply-to If set, the replies will all be to the previous
  68                  email sent, rather than to the first email sent.
  69                  Defaults to on.
  70
  71   --signed-off-cc Automatically add email addresses that appear in

  75                  the default section.
  76
  77   --smtp-server  If set, specifies the outgoing SMTP server to use.
  78                  Defaults to localhost.  Port number can be specified here with
  79                  hostname:port format or by using --smtp-server-port option.
  80
  81   --smtp-server-port Specify a port on the outgoing SMTP server to connect to.
  82
  83   --smtp-user    The username for SMTP-AUTH.
  84
  85   --smtp-pass    The password for SMTP-AUTH.
  86

  90                  can be one of 'author' for the patch author, 'self' to
  91                  avoid copying yourself, 'sob' for Signed-off-by lines,
  92                  'cccmd' for the output of the cccmd, or 'all' to suppress
  93                  all of these.
  94
  95   --suppress-from Suppress sending emails to yourself. Defaults to off.
  96
  97   --thread       Specify that the "In-Reply-To:" header should be set on all
  98                  emails. Defaults to on.
  99
 100   --quiet        Make git-send-email less verbose.  One line per email
 101                  should be all that is output.
 102
 103   --dry-run      Do everything except actually send the emails.
 104
 105   --envelope-sender    Specify the envelope sender used to send the emails.
 106
