sorry hit the send before i'd finished.
 
what you need is a protocol rule allowing outbound smtp for the ip
address of the smtp server

Ok well I have a Packet filter created to allow SMTP outbound as
follows: 

ISA server

Filter type: Custom - TCP

Direction: Outbound

Local port: Dynamic

Remote Port: Fixed

Remote Port Number: 25

Local Computer: ISA server external IP

Remote Computer: All remote computers

 

What else do I need to do to enable this function because it doesn't
appear to be working? I must be missing something here. Any links or
articles? 

 

Thanks

you don't need to publish it if it's only for outgoing mail, you can't
publish more than one anyhow.

http://www.ISAserver.org

I need some help publishing an SMTP server through ISA. Anytime I
attempt to create the secure mail server I get the following error: 

ISA Server cannot save the properties

There is already a rule that defines a mapping for the external port and
IP address specified. 

 

All I'm trying to do is enable my postnuke website, which resides on a
separate server, to send mail to users that attempt to join the site. I
have a separate internal exchange server published thru ISA that hosts
mail for mail.nusolutions.net. This new site is nubiint.com. 

I have an SMTP Relay filter installed on the ISA server and the Message
Screener configured for the internal mail server. 

I installed the SMTP service on the web server and configured it to use
its internal IP

I have a total of 3 static IP's assigned to the external interface: 

  Gateway

  www.mysite.com

  mail.mysites.com

I installed the Message Screener on the SMTP, web, server.

I created a new domain, the same mail domain as the internal mail
server, mail.nusolutions.biz, under Default Virtual Server 

I copied and ran SMTPCred.exe on the SMTP, web, server

I attempt to publish the server as a secure mail server using the
following options: 

  Publish these mail services: Incoming SMTP

  External IP of ISA: 205.179.209.99 same one used for
mail.nusolutoions.biz

  At this IP address: IP of SMTP, web, server

I already have a SMTP Filter and Relay rule published using the same IP
of the external interface. 

 

What am I doing wrong? Do I have to add another static IP to the
interface of the ISA and use it? 

 

Any responses are appreciated. 

Thanks
