CentOS - Apr 2007 - sendmail smrsh symlinks not working against php scripts

Hello.

I am trying to forward the e-mails received to one address towards a php 
script.
I am trying all I can but nothing does.

I have edited my /etc/aliases file and added this line.
ecard-bounce: "|/usr/bin/php /etc/smrsh/ecardbounce.php"

Then, of course I do a 'newaliases'.
In my /etc/smrsh I have placed the symbolic link defined above, which has 
been created this way:
ln -s /home/my/scripts/ecardbounce.php /etc/smrsh/ecardbounce.php

When using this configuration, I get the following error back by email:

   ----- The following addresses had permanent fatal errors -----
"|/usr/bin/php /etc/smrsh/ecardbounce.php"
    (reason: 255)
    (expanded from: <ecard-bounce at myserver.com>)

   ----- Transcript of session follows -----
Status: 404
Content-type: text/html
X-Powered-By: PHP/4.3.9

No input file specified.
554 5.3.0 unknown mailer error 255



However, if I put a hardlink instead of the symlink, all works fine!
The permissions of the symlink and the file linekd are all 777.

Has anyone already had this problem before, or would anyone have an idea of 
the problem?

Thanks,
Daniel

Wouldn't smrsh need to include /usr/bin/php as well in its 
permitted subshell applications links in /etc/smrsh/?  the 
object of the binary is not checked -- the binary is

Note:  I do not pass on the security advisability of this act, 
just sendmail syntax

It has been a long time since I added items to the sendmail 
permitted applications list as it is a known scurity cesspool.
