NAME

6       innmail - Simple mail-sending program
7

SYNOPSIS

9       innmail [-h] [-a header] [-s subject] address [address ...]
10

DESCRIPTION

12       innmail is a Perl script intended to provide the non-interactive mail-
13       sending functionality of mail(1) while avoiding nasty security
14       problems.  It takes the body of a mail message on standard input and
15       sends it to the specified addresses by invoking the value of mta in
16       inn.conf.
17
18       At least one address (formatted for the MTA specified in inn.conf, if
19       it matters) is required.  innmail will sanitize the addresses so that
20       they contain only alphanumerics and the symbols "@", ".", "-", "+",
21       "_", and "%".
22
23       innmail was written to be suitable for the mailcmd setting in inn.conf.

OPTIONS

26       -a header
27           Specifies an additional header field to add in the headers of the
28           message.  It should be a well-formed header field surrounded by
29           quotes, consisting of a name and a body separated with a colon and
30           a space.  For instance, "Auto-Submitted: auto-generated" is used by
31           some programs invoking innmail.
32
33           You may provide more than one header field if header is a multi-
34           line string, which can for instance be done with these commands:
35
36               HEADERS=$(echo -e "Hdr1: Body1\nHdr2: Body2")
37               echo "test" | innmail -a "$HEADERS" -s Test joe
38
39       -h  Gives usage information.
40
41       -s subject
42           Sets the Subject header field body of the message.  A warning is
43           issued if this option is omitted.
44

EXAMPLES

46       This sends a one-line message to the local user "joe":
47
48           echo "A one-line message." | innmail -s "Simple message" joe
49
50       innmail by default is used by INN for sending nightly reports to the
51       news administrator, as well as errors during the execution of a few
52       programs.
53

BUGS

55       innmail fails on addresses that begin with "-", although one might hope
56       that the news server will not need to contact any such addresses.
57
58       There are many "correct" addresses that will be silently modified by
59       the sanitization process.  A news administrator should be careful to
60       use particularly sane addresses if they may be passed to innmail.
