innmail - Simple mail-sending program
SYNOPSISinnmail [-h] [-s subject] address [address ...]
DESCRIPTIONinnmail is a Perl script intended to provide the non-interactive mail-sending functionality of mail(1) while avoiding nasty security problems. 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 "%".
- Gives usage information.
- -s subject
- Sets the Subject: header of the message. A warning is issued if this option is omitted.
EXAMPLESThis sends a one-line message to the local user "joe":
echo "A one-line message." | innmail -s "Simple message" joe
BUGSinnmail 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.
