Thanks 

Ok, I can delete the existing Mail wizard rule but I think what has me
confused is that I'm to add the IP of the ISA server's internal IP
instead of the IP of the internal exchange server. Is this correct
because the IP of the internal exchange server is what's working now. Or
am I in left field?

Thanks

Hi Marvin,

Disable all the rules created by the Wizard. You can to manually publish
the SMTP service that is listening on the Internal interface. I don't
recall exactly how the Wizard does things, but I think it creates packet
filters, not publishing rules when the SMTP server is identified as
being on the ISA firewall.

HTH,
Tom

Or do you mean I should disable or remove the SMTP application filter?

Socket pooling has been disabled, I don't have any SMTP packet filters
in place and the SMTP service is listening on the internal interface of
the firewall. The only server publishing rule I have is the Mail wizard
rule which is pointing to an IP on the external interface of the ISA
server and listening on the internal IP of the mail server. This rule is
using the SMTP protocol. Will disabling this one effect incoming mail
flow or am I in left field? 
 
Thanks

Hi Marvin,
 
Disable all the other SMTP rules you have in place, and remove any SMTP
related packet filters you have, unless you're using the packet filter
approach to publishing the SMTP server. Make sure that socket pooling is
disabled for the SMTP service too.
 
Also, make sure the SMTP service is listening on the Internal interface
of the ISA firewall. Not "all IP addresses".
 
HTH,
Tom

In trying to follow documentation to create an SMTP server publishing
rule to create an SMTP filter and relay as listed here: 
http://isaserver.org/tutorials/messagescreeneronfirewallpart2.html
 
I get an error stating:
ISA server cannot save the new object
There is already a rule that defines a mapping for the external port and
IP address specified. 
 
I configure this rule with the following settings: 
IP Address of internal interface of the ISA server.
IP on external interface of ISA server that handles mail. 
 
Apply rule to SMTP server
Apply rule to Any request 
 
I notice that there is already a Mail wizard rule in place, but it lists
the IP of the internal mail server and not the internal interface of the
ISA server. 
I've followed the steps as outlined in part 1 of this article so what
could I be missing here? 
Any feedbacks appreciated
 
Thanks
