SYNOPSIS

setmaillist bin tmp

DESCRIPTION

setmaillist reads a mailing list from its standard input.

setmaillist writes the mailing list in a binary format to tmp; it then moves tmp to bin. tmp and bin must be on the same filesystem.

If there is a problem creating tmp, setmaillist complains and leaves bin alone.

The binary mailing list format is portable across machines.

setmaillist always creates bin world-readable.

MAILING LIST FORMAT

The mailing list read by setmaillist is a series of lines. NUL bytes are not allowed.

If a line begins with a dot or slash, setmaillist takes the entire line as an include file name.

If a line begins with an ampersand, setmaillist takes the rest of the line as a recipient address. If a line begins with a letter or number, setmaillist takes the entire line as a recipient address. Each recipient address must include a fully qualified domain name. Recipient addresses longer than 800 bytes are not allowed.

setmaillist ignores blank lines and lines beginning with #. It also ignores spaces and tabs at the ends of lines.

For example,

   [email protected]
   [email protected]

is a mailing list with two addresses.
