Redirecting email to a Script

    [ The following text is in the "iso-8859-1" character set. ]
    [ Your display is set for the "US-ASCII" character set.  ]
    [ Some characters may be displayed incorrectly. ]


You log file shows sendmail is trying to use "|/post_leads_to_sugar".


I have a working script in place, it does not do anything useful but
maybe this will help:


Email address: blockme at mail.crackerbarrel.com 
Script: /sbin/spamtest



ls -lia /etc/smrsh/spamtest:
99990 lrwxrwxrwx    1 root     root           14 Oct 23  2003 spamtest ->
/sbin/spamtest

grep spamtest /etc/aliases:
blockme:        "|/sbin/spamtest"


Email to blockme at mail.crackerbarrel.com is passed to /sbin/spamtest
script:
#!/bin/sh

Subject: Redirecting email to a Script


Brief overview:
        Mailscanner system in front of an exchange server.  I'm trying
to get email to activate a script via an alias when an email comes in.


Right now I've got /etc/aliases set up w/:

somebody:          "| /post_leads"

Then I did a newaliases.



I have a symbolic link in /etc/smrsh pointing to the real script.
Here's a ls -lah

[root at computername smrsh]# ls -lah
total 12K
drwxr-xr-x   3 root root 4.0K May 12 13:36 .
drwxr-xr-x  57 root root 4.0K May 12 13:42 ..
lrwxrwxrwx   1 root root   35 May 12 13:36 post_leads ->
/nobody_scripts/post_leads


The nobody_scripts is a temp directory w/ bad permissions (777), but I
just want to get it working. ls -lah:

[root at computername nobody_scripts]# ls -lah
total 12K
drwxrwxrwx   2 root root 4.0K May 12 13:36 .
drwxr-xr-x  22 root root 4.0K May 12 13:36 ..
-rwxrwxrwx   1 root root    0 May 12 13:28 out.txt
-rwxrwxrwx   1 root root   32 May 12 13:29 post_leads



And finally, here's the script:
#/bin/bash
echo $1 >> out.txt
