Options: --from Specify the "From:" line of the email to be sent. --to Specify the primary "To:" line of the email. --cc Specify an initial "Cc:" list for the entire series of emails. --bcc Specify a list of email addresses that should be Bcc: on all the emails. --compose Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit an introductory message for the patch series. --subject Specify the initial "Subject:" line. Only necessary if --compose is also set. If --compose is not set, this will be prompted for. --in-reply-to Specify the first "In-Reply-To:" header line. Only used if --compose is also set. If --compose is not set, this will be prompted for. --chain-reply-to If set, the replies will all be to the previous email sent, rather than to the first email sent. Defaults to on. --signed-off-cc Automatically add email addresses that appear in Signed-off-by: or Cc: lines to the cc: list. Defaults to on. --smtp-server If set, specifies the outgoing SMTP server to use. Defaults to localhost. --suppress-from Suppress sending emails to yourself if your address appears in a From: line. Defaults to off. --thread Specify that the "In-Reply-To:" header should be set on all emails. Defaults to on. --quiet Make git-send-email less verbose. One line per email should be all that is output. --dry-run Do everything except actually send the emails. --envelope-sender Specify the envelope sender used to send the emails.
