one warning when implementing this solution... if you directly forward your email to the receiving smtp servers then you may have trouble with service providers that require reverse dns lookup... Service providers would likely reject your request due to not being to resolve a domain name to your ip address... this is a security feature many service providers had begun using to try to limit spam to their users from unscrupulouis persons abusing email servers such as the one your attempting to implement...

hmnn  I am trying to test the service on my pc on port 25 using Microsoft Internet Information Services (IIS) and Microsoft SMTP Service,  and message is queued but never gets to the destination and there are no errors reported...

Any ideas?
in the queue right click the message and click force connection... and see if it goes out then...
You could try using this instead of windows smtp service, its fee and realy simple to setup, when asked for your SMTP server use localhost.

You can install the SMTP Service that comes with Windows 2000 and XP and use it locally, but there are many cavets...

First, you have to configure it so it is not an open relay and so it does allow everybody (aka spammers) to start using your computer to relay messages through you like the 225000 people listed by

Next, you have to configure it so bounces are actually sent back to you or the appropriate person the message was sent from.

Next, you'll find that you may not only need Reverse DNS setup but you may be blocked because you are on a dynamic/consumer class network and listed on a Dialup/Dynamic Black List like SORBS or DSBL.

You can check your current IP by checking it on or which is a compilation of 30 or so major block lists including ORDB, SORBS, and DSBL.

You may be unable not send mail if your domain it setup for SPF (

Many ISPs slow down or outright block outgoing access from the SMTP port 25 leaving their networks because of SPAM and Virus problems so that may preclude the option entirely.

A good test would be to go to dos and try this...


If you can connect and then if you don't get disconnected after 3 seconds with a message like...

554- (RTR:BB)
554- AOL does not accept e-mail transactions from dynamic or residential
554- IP addresses.
554  Connecting IP:

or something complaining about you not having a reverse DNS then you can start trying things.

The question is not if you can do it, but rather why you want to do it or why do think you need to do it.
The answer would be you don't need to do it.
