If no argument is given on the command line, ezmlm-sub processes stdin.

If box@domain is already on the mailing list, ezmlm-sub leaves it there and does not modify the subscription log.

ezmlm-sub converts domain to lowercase before adding box@domain to the mailing list.

box@domain cannot be longer than 400 characters (255 characters with mysql support).

-n

Assume arguments are pairs of box@domain and name (or other subscriber info) rather than addresses alone. ezmlm-sub(1) will add the first argument in each pair to the subscriber list. If it is a new address, name will be added to the subscription log.

-N

(Default.) Arguments are all addresses of the type box@domain.

-v

Display ezmlm-sub(1) version information.

-V

Display ezmlm-sub(1) version information.

-h hash

With mysql support the argument is used as the hash. The argument should be between 1 and 99. The hash is used in in the distribution of addresses between sublists. As the hash is normally between 0 and 52, controlling the hash makes it possible to add addresses that cannot be manipulated remotely.

-m

(Default.) Use SQL support if available.

-M

Do not use SQL support even if available. This option can be used to build a normal local subscriber database even for lists with SQL support. Use in combination with ezmlm-list(1) to convert an SQL address db to a ezmlm standard address database.
