Thanks Nick.

Did all that. Now fetchmail hands over the mail to port 25 smtp than it is
handed over to procmail after scanning. Everything works fine. Thanks a
lot.

However one problem. Whenever a virus is detected a mail is sent to the
sender of the mail telling him that his machine is infected. But the mail
is going as

---------------------------------------------------------------------------
From: "MailScanner" <postmaster at debian.home>
Date: Tue, 14 May 2002 21:53:37 GMT
To: <horacio at cerealesquemu.com.ar>
Subject: Warning: E-mail viruses detected

Our virus detector has just been triggered by a message you sent:-
  To: <rajesh at localhost>
  Subject: A very  powful tool
  Date: Tue May 14 21:53:37 2002
Any infected parts of the message have not been delivered.

This message is simply to warn you that your computer system may have a
virus present and should be checked.

The virus detector said this about the message:
Report: /var/spool/mailscanner/incoming/g4ELq8pi000692/align.scr
Infection: W32/Klez.H at mm
---------------------------------------------------------------------------

As you can see, it is going as postmaster at debian.home ( here debian.home is
a fictitous domain name on my home machine ). Due to this sendmail is not
sending the mail to the actual sender but bounces back.

What changes in configuration should I do to the mailscanner so that the
from address domain is a valid domain. I don't seem to find the setting
required for this.

Can anybody help ?

Thanks in advance.

Sorry for the long mail.

Peace
