This depends on your configuration. In my case yes. I have: User=>MTA=>ASSP=>MS SMTP=>Internet This differs in a key way from the other accepted configuration of: User=>ASSP=>MTA=>Internet If your MTA has an integrated web mail feature you may have to use the first configuration if you want the web mail to be seen by ASSP for auto-whitelisting of recipients. Since you mentioned a smarthost, it sounds like you might be using Exchange, and in fact your email headers seem to corroborate that fact, so your configuration is similar to the web mail config and you have to configure sending through a smarthost which goes through ASSP first and then an SMTP sending service of your choice, I'll use MS SMTP for the example: User=>Exchange=>smarthost (ASSP relay port)=>MS SMTP=>Internet See: http://www.asspsmtp.org/wiki/Configuration http://www.asspsmtp.org/wiki/HOWTOS#Microsoft_Exchange_HOWTOs And here is a Google cache write-up on using ASSP with Exchange: http://tinyurl.com/2oe7ab or http://72.14.253.104/search?q=cache:TQZbdJXokKsJ:www.andersonit.com/assp/ASSP%2520Installation%2520with%2520Exchange%25202000.doc+assp+installer&hl=en&ct=clnk&cd=2&gl=us&lr=lang_en http://www.andersonit.com/assphowtoe2k.htm > 2. If ASSP listens on only 1 port , how can it distinguish between > incoming and outgoing SMTP actions? (Or does relay have to be set) Relay listen port is different than the Listen port. ASSP has another listen port for outgoing connections to be sent from your MTA to ASSP. Depending on who is sending through ASSP you may or may be connecting to it from outside of your local network. I have one network that allows email to be sent from outside the network. Those users connect to port 587 of my server which goes directly to my MTA'a authentication port. Mail is then routed internally or externally as needed, only external mail goes through ASSP. I have another site sending email from inside only, so they connect to their MTA's SMTP listen port which is not available to the internet. Then the MTA sends the email internally or externally, with external mail being routed through ASSP. In both these cases, routing the external mail calls for the MTA to send to ASSP's relay listen port which is not available to the Internet and then ASSP hands that off to the SMTP delivery service which is also not available to the Internet. If you don't use Auth and have external users sending through your server (why would you?) you could have then connect to the same SMTP port that you are receiving email on for your domain. ASSP would pass it along to your MTA (Exchange) and then it would get routed to the intended recipient. The best practice is to have authorized sending users to connect directly to your MTA with the email bypassing ASSP until the MTA is routing it out to the Internet.
