innmail - Simple mail-sending program
innmail [-h] [-s subject] address [address ...]
innmail is a Perl script intended to provide the non-interactive mail-
sending functionality of mail(1) while avoiding nasty security prob-
lems. It takes the body of a mail message on standard input and sends
it to the specified addresses by invoking the value of mta in inn.conf.
At least one address (formatted for the MTA specified in inn.conf, if
it matters) is required. innmail will sanitize the addresses so that
they contain only alphanumerics and the symbols "@", ".", "-", "+",
"_", and "%".
innmail was written to be suitable for the mailcmd setting in inn.conf.
-h Gives usage information.
Sets the Subject: header of the message. A warning is issued if
this option is omitted.
This sends a one-line message to the local user "joe":
echo "A one-line message." │ innmail -s "Simple message" joe
innmail by default is used by INN for sending nightly reports and con-
trol message reports.
innmail fails on addresses that begin with "-", although one might hope
that the news server will not need to contact any such addresses.
There are many "correct" addresses that will be silently modified by
the sanitization process. A news administrator should be careful to
use particularly sane addresses if they may be passed to innmail.
