Hi All
Just finish and success installing ASSP, I would like to implement this normal method
Internet --(25)-->Firewall --(25)-->ASSP--(125)-->HMailServer--(125)-->Firewall--->Internet
Firewall = Win2003 with ISA 2006
ASSP & HMailServer = Win 2003 ( same computer )
After I deploy the ASSP and start the service outside email cannot arrive to my mail server
Gmail Return :
The error that the other server returned was: 530 530 Relaying not allowed (state 14)
From what I understand :
1. The relay from port 25 to 125 inside ASSP is not working cuz I set it wrong
2. If it possible to do relaying inside one computer ( same IP different Port ) ?
Sorry for being late on this

My suggestion is to setup things as follows:
Install the "Microsoft Loopback adapter" and set it up with a private IP falling
inside a private subnet not used by you; for example 172.30.254.254/24
Install the Microsoft IIS SMTP service and bind it to 172.30.254.254:125
Install the hMailServer and bind it to 172.30.254.254:225
Install ASSP and bind it to your public/main IP on ports 25, 465 (listeportSSL)
and 587 (listenport2), set "smtpdestination" to 172.30.254.254:225, do the
same with "smtpdestinationSSL" and "smtpAuthServer" check it's working by
running a telnet against the port 25 of the box, you should get back your
hMailServer prompt
Now set ASSP "relayport" to 172.30.254.254:25 and also set the ASSP "relayhost"
to 172.30.254.254:125 (aka the IIS SMTP listen address); try running telnet against
172.30.254.254:25 and if all ok, you should see the IIS SMTP banner
Configure hMailServer to use 172.30.254.254:25 as the smarthost for all the outgoing
email messages
Now, ensure that both hMailServer and the IIS SMTP allow relaying from 172.30.254.254
also, edit the ASSP "localDomains" and enter all the domains you're handling locally
You're done; your mail flow will now look as follows
* Incoming
sender -> <public-ip>:25 (ASSP) -> 172.30.254.254:225 (hMailServer)
* outgoing
172.30.254.254 (hMailServer) -> 172.30.254.254:25 (ASSP relayport) -> 172.30.254.254:125 (IIS SMTP) -> external destination
