Few computers in my LAN are Virus  infected and generating e-mail automatically throughing the same subject(e.g My photo in Paris).In my ISA server I have Mail Essentials(G.F.I) installed and added the subject in the subject rule for that mail is not coming from outside network having this subject.But the problem that i am facing,  E-mail is generating automatically from internal virus infected PC  having that subject and sending to other internal clients.If i can create any subject blocking rule in exchange server 2003 then the problem can be resolved.How can I define subject rule in exchange server 2003 to block a subject and Which server I need to define FE or BE.

 My Existing Schenario is Internet - ISA server -FE Exchange server -Backend Exchange server.

Please suggest me.

You need to use some content management tool in exchange 2003. There is nothing inbuilt available.

How do you know the messages are not being generated from outside? Remember that most viruses spoof everything.
Furthermore, it is very unusual for a virus to use internal servers and Outlook connections to spread. Most of them have their own SMTP engine. Having the messages delivered internally would only happen if you have an MX record on your internal DNS that points to your Exchange server.

If you suspect that you have a machine inside infected, then simply block port 25 on the firewall for all machines but the Exchange server. An infected machine will soon show up in the logs.
