Hey Zafar,

 

You already have a webshield server in front of Exchange? Yes, Webshield has
its own SMTP server, it doesn't need IIS for anything. It's really easy to
configure it, all you need to do is tell it if the mail server is on the
same machine or on other machine, configure for which domains it should
deliver mail internally, configure what's your internal IP range and you're
protected. It works really well. 

 

The only problem is that this solution will tie you up, meaning that you
won't be able to implement any other kind of defense on this server, and
it'll hit the CPU hard.

 

No need to be concerned about Open Relays and other security threats.
Webshield will deal with these problems very well.

Thanks for your kind reply.

 

I have few doubt coz I m new with webshield . I'll be placing my webshield
server behind my PIX without any ISA and in front of my Exchange 5.5. I
guess webshield have its own SMTP services and do not use IIS SMTP. My
concern about Open Relay and other security threats. Please throw some light
on this. Of course GFI is the best option. 

 

Thanks

Zafar

Damn Chris, you didn't need to hammer Webshield =)

 

My two customers have Webshield for SMTP and it acts as an SMTP server. It
catches every virus that knocks on their door, but I think that the stress
made on the machine with ISA + Webshield isn't worth it. And forget about
using it as an anti-spam solution. Too poor.

 

My ISA with eTrust and GFI MailEssentials can still run on an IBM Netfinity
3000 (Pentium II-266), because it can't hit much more than 10% of CPU usage.
I guess eTrust AV7 + ME9 would definitely solve every problem you have
there.

 

But, if you buy MailEssentials+MailSecurity, GFI has a bundle that is a
killer. I would suggest you this solution in top of any other.
