# Sends a collection of emails to the given email addresses, disturbingly fast.

# Supports two formats:

# 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)

# 2. The original format support by Greg's script:
|
|
# first line of the message is who to CC,
|
|
# and second line is the subject of the message.

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.
|
|
|
|
--compose Use \$EDITOR 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.
|
|
|
|
--no-signed-off-cc Suppress the automatic addition of email addresses
|
|
that appear in a Signed-off-by: line, to the cc: list.

--smtp-server If set, specifies the outgoing SMTP server to use.
|
|
Defaults to localhost.
|
|
|
|
--suppress-from Supress sending emails to yourself if your address
|
|
appears in a From: line.
|
|
|
|
--quiet Make git-send-email less verbose. One line per email should be
|
|
all that is output.
