I wish to use sendmail without having to specify # print "From: user1@`hostname`" so that it picks or formulates the default value of From: which is in most cases the
Quote:
username@hostname
Can you help tweak the script to default the From: aspect ?

I found this nice... (2 Replies)

smrsh
SMRSH(8) System Manager's Manual SMRSH(8)NAME
smrsh - restricted shell for sendmail
SYNOPSIS
smrsh -c command
DESCRIPTION
The smrsh program is intended as a replacement for sh for use in the ``prog'' mailer in sendmail(8) configuration files. It sharply limits
the commands that can be run using the ``|program'' syntax of sendmail in order to improve the over all security of your system. Briefly,
even if a ``bad guy'' can get sendmail to run a program without going through an alias or forward file, smrsh limits the set of programs
that he or she can execute.
Briefly, smrsh limits programs to be in a single directory, by default /etc/smrsh, allowing the system administrator to choose the set of
acceptable commands, and to the shell builtin commands ``exec'', ``exit'', and ``echo''. It also rejects any commands with the characters
``', `<', `>', `;', `$', `(', `)', `
' (carriage return), or `
' (newline) on the command line to prevent ``end run'' attacks. It allows
``||'' and ``&&'' to enable commands like: ``"|exec /usr/local/bin/filter || exit 75"''
Initial pathnames on programs are stripped, so forwarding to ``/usr/ucb/vacation'', ``/usr/bin/vacation'', ``/home/server/mydir/bin/vaca-
tion'', and ``vacation'' all actually forward to ``/etc/smrsh/vacation''.
System administrators should be conservative about populating the /etc/smrsh directory. For example, a reasonable additions is vaca-
tion(1), and the like. No matter how brow-beaten you may be, never include any shell or shell-like program (such as perl(1)) in the
/etc/smrsh directory. Note that this does not restrict the use of shell or perl scripts in the sm.bin directory (using the ``#!'' syntax);
it simply disallows execution of arbitrary programs. Also, including mail filtering programs such as procmail(1) is a very bad idea.
procmail(1) allows users to run arbitrary programs in their procmailrc(5).
