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

Composing:
--from <str> * Email From:
--[no-]to <str> * Email To:
--[no-]cc <str> * Email Cc:
--[no-]bcc <str> * Email Bcc:
--subject <str> * Email "Subject:"
--reply-to <str> * Email "Reply-To:"
--in-reply-to <str> * Email "In-Reply-To:"
--[no-]xmailer * Add "X-Mailer:" header (default).
--[no-]annotate * Review each patch that will be sent in an editor.
--compose * Open an editor for introduction.
--compose-encoding <str> * Encoding to assume for introduction.
--8bit-encoding <str> * Encoding to assume 8bit mails if undeclared
--transfer-encoding <str> * Transfer encoding to use (quoted-printable, 8bit, base64)
Sending:
--envelope-sender <str> * Email envelope sender.
--sendmail-cmd <str> * Command to run to send email.
--smtp-server <str:int> * Outgoing SMTP server to use. The port
is optional. Default 'localhost'.
--smtp-server-option <str> * Outgoing SMTP server option to use.
--smtp-server-port <int> * Outgoing SMTP server port.
--smtp-user <str> * Username for SMTP-AUTH.
--smtp-pass <str> * Password for SMTP-AUTH; not necessary.
--smtp-encryption <str> * tls or ssl; anything else disables.
--smtp-ssl * Deprecated. Use '--smtp-encryption ssl'.
--smtp-ssl-cert-path <str> * Path to ca-certificates (either directory or file).
Pass an empty string to disable certificate
verification.
--smtp-domain <str> * The domain name sent to HELO/EHLO handshake
--smtp-auth <str> * Space-separated list of allowed AUTH mechanisms, or
"none" to disable authentication.
This setting forces to use one of the listed mechanisms.
--no-smtp-auth Disable SMTP authentication. Shorthand for
`--smtp-auth=none`
--smtp-debug <0|1> * Disable, enable Net::SMTP debug.
--batch-size <int> * send max <int> message per connection.
--relogin-delay <int> * delay <int> seconds between two successive login.
This option can only be used with --batch-size
Automating:
--identity <str> * Use the sendemail.<id> options.
--to-cmd <str> * Email To: via `<str> \$patch_path`.
--cc-cmd <str> * Email Cc: via `<str> \$patch_path`.
--header-cmd <str> * Add headers via `<str> \$patch_path`.
--no-header-cmd * Disable any header command in use.
--suppress-cc <str> * author, self, sob, cc, cccmd, body, bodycc, misc-by, all.
--[no-]cc-cover * Email Cc: addresses in the cover letter.
--[no-]to-cover * Email To: addresses in the cover letter.
--[no-]signed-off-by-cc * Send to Signed-off-by: addresses. Default on.
--[no-]suppress-from * Send to self. Default off.
--[no-]chain-reply-to * Chain In-Reply-To: fields. Default off.
--[no-]thread * Use In-Reply-To: field. Default on.
Administering:
--confirm <str> * Confirm recipients before sending;
auto, cc, compose, always, or never.
--quiet * Output one line of info per email.
--dry-run * Don't actually send the emails.
--[no-]validate * Perform patch sanity checks. Default on.
--[no-]format-patch * understand any non optional arguments as
`git format-patch` ones.
--force * Send even if safety checks would prevent it.
Information:
--dump-aliases * Dump configured aliases and exit.
