need help modifying shell script

[Chris Yuzik]

Hi guys and gals,

While I'm not bad at Perl, I admit that I suck at bash shell scripting. 
Here's the scoop. As I discovered and pointed out in a previous thread, 
some mail is being picked up by sendmail and sneaking right through the 
spam/virus checks and getting plopped into the users' mailboxes. 
Obviously not a good situation.

I've attached a zip that contains the existing MailScanner_app_init 
that's currently running on the system, as well as the new one from the 
rpm. I've also included sendmail_app_init that came with the system. 
I've tried stopping sendmail, then disabling the sendmail_app_init 
script and starting MailScanner from MailScanner_app_init_rpmnew but 
mail can't get in to the server.

The problem I'm having is that the existing MailScanner_app_init doesn't 
start up the necessary sendmail daemon to listen for incoming email on 
port 25; that seems to happen in sendmail_app_init. The 
MailScanner_app_init_rpmnew does say it starts sendmail, but doesn't 
start anything that listens for incoming mail (kind of an important part 
for a mail server :).

I presume I just need to find the part of sendmail_app_init that starts 
the sendmail daemon listening on port 25 and insert that line (or lines) 
into the MailScanner_app_init_rpmnew file and using that instead of the 
stock one. Problem is, I'm going bleary-eyed trying to figure this out 
and I think I'm gonna break something baaad.

If any of you are good at shell scripting, I would really appreciate 
some help.

Thanks,
Chris
