You can't turn off anonymous emails, otherwise SpamFilter will not be able to receive emails from the internet, as mail servers "talk" regular anonymous SMTP.
If a client supports SMTP authentication, and it's enabled, the client will make a EHLO request to the server (SpamFilter). The server will respond with a welcome banner, indicating in it that it supports AUTH LOGIN (smtp authentication). The client should see that, and thus attempt to use authentication:

  <<EHLO test.logsat.com
  >>250-AUTH LOGIN
  >>250-8BITMIME
  >>250-SIZE 1024
  >>250 HELP

It is up to the client to send the auth commands. You could try to use SpamFilter's debug tab to capture the traffic to/from the client to see what is going on.

SpamFilter needs to know the domain name for Active Directory so it canlocate your Domain Controllers to authenticate. As with ActiveDirectory you could have child domains, and trusts with other domains,a fully qualified username (domain\user or user@domain) is required touniquely identify the user.

I believe the DameWare Utilities allow you to rename services.

Alternatively, you can use the INSTSRV.exe utility from the Microsoft resourcekit to install the second service with a different name:

C:\Program Files\SpamFilter2>instsrv SpamFilter2 "c:\program files\spamfilter2\spamfiltersvc.exe"

When you do this, ensure you change the service properties after it's created to "Allow service to interact with desktop"

The sc.exe utility from MIcrosoft allows you to create services as well.

It's as simple as
1. copying/installing SpamFilter in a new different directory.
2. Rename the first SpamFilter NT service, so it won't be overwritten by the new service.
3. Start the new SpamFilter in stand-alone mode (using SpamFilter.exe), and configure it to use a different IP or port
4. Click on the "Create Service" button.

You can run a few dozen instances if you want

that is exactly what i'm suggesting.. and Roberto won't mind at all since the license is 'per server', I even 'heard' him say so himself in here some time ago :)

You will need (if you think you need it) a different database, and setup SF2 so that it listens on a different IP/port, and install it in a directory with a different name, as far as i know that is all it takes.

There have been discussions about running SF twice on the same box in this forum, better look them up for more details, i never had a need for dual sf, but i know it is doable, and fairly easy for that matter also.

Marco,

 

Are you suggesting that I could run a second instance os SF on the same box??

How would I install the service?? It would need to ahve a different name to the first one, and presumably be installed in a different folder as it will need a slightly different config.

Am I getting this right, or have I completely lost the plot?????

maybe you should run a second instance of SF, on a port other than 25, and make thise second instace treat your 'incoming' mail (from this customer) as usual for incoming mails from internet....  when the mails from this source is found O.K. relay it to your primary SF and use its SMTP feature.

any internal spammers should be picked up by this second instance (uses all the regular sf features, except some IP based ones) before they are sent to the outside world. If you set it up correctly you should be able to identify the  offending internal ip from the 2nd instance's logs/QDB/FROM mail addy.

 

Setup your firewall so that no outside IP can send mails directly to this second instance ofcourse.

If i got this right in my head i think you should be able to filter all your 'internal' customers by making them use  this internal spamfilter.

Just a suggestion, maybe i got it all wrong here and am talking rubbish (that wouldn't be a first)

OK, just to clarify....

I presume that most of the spam detection relates to where the email origionates from, rather than the content of the email. Therefore what would be the best way to detect spam comming from an internal source?? (my client would effectively be an internal source if he relayed through me).?

 

cheers
