Re: [Assp-user] Assp hmailserver cannot send emails

Nice setup but wouldn't that mean that all clients would have to change
their outbound port to 125?

hm... sounds like there may be some problem with the config; didn't check
your config (also since the ML strips off attachments - and in any case,
better NOT sending around your config ;-D) but I strongly suspect that
you'll need to revise your mailflow setup; my suggestion is the following:

1. Install the "MS Loopback adapter" on your hmailserver box and set it
   up using a subnet different from any other in use; for example, set
   it up as 172.20.8.25/255.255.255.0 (no gateway, no DNS)

2. Ensure that hMailServer SMTP is ONLY listening on 172.20.8.25:8025

3. Ensure that ASSP is listening on <public>:25 where <public> is the
   public IP address for your mailserver

4. Configure the ASSP mail host to be 172.20.8.25:8025 (hMailServer)

5. telnet to your mailserver:25 if all is working ASSP will log the
   connection AND you'll also see the banner from your hMS

6. Stop ASSP, Install the IIS SMTP, configure it to listen on
   172.20.8.25:9025, start ASSP

7. Configure ASSP to use 172.20.8.25:9025 as the relayhost

8. Bind the relayport in ASSP to 172.20.8.25:125

9. Configure hMailServer to use 172.20.8.25:125 as the smarthost for
   outgoing email delivery

using the above configuration, your mail flow will be the following

* Inbound

Sender => ASSP:25 => hMailServer:8025

* Outbound

hMailServer => ASSP:125 => IIS_SMTP:9025 => destination MX

HTH
