Add members from a file to a mailman list. Listname is the name of the Mailman list you are adding members to. It must already exist.
A file containing addresses of the members to be added, one address per line. This list of people become non-digest members. If file is `-', read addresses from stdin. Note that -n/--non-digest-members-file are deprecated synonyms for this option.
Similar to above, but these people become digest members.
Set whether or not to send the list administrators a notification on the success/failure of these subscriptions, overriding whatever the list's `admin_notify_mchanges' setting is.
Set whether or not to send the list members a welcome message, overriding whatever the list's `send_welcome_msg' setting is.
Print a help message and exit.
You must supply at least one of -r and -d options. At most one of the files can be `-'.
