Anti-Spam SMTP Proxy

In April 2007, we have installed ASSP with ASSP Deluxe on all our non-dedicated servers.

Since then, the amount of SPAM received by most of our clients has radically reduced, but some clients have complained about false positives, or valid e-mails rejected improperly.

95% of our clients who received false positives were not using their own domains as their SMTP server, preventing ASSP from learning which e-mails were valid, and which were not.

Another advantage with ASSP is that unlike in the past, e-mails rejected are now bounced instead of being discarded, so that the senders know if you didn't get his or her e-mail.

Set your own domain for your SMTP server

For ASSP to work properly, you need to :

  • set your SMTP server in your mail client (such as Outlook) to : yourdomain.com,
  • activate authentication on your outgoing mail server,
  • if port 25 is blocked, try port 26.

How to whitelist an e-mail address

Once you have activate authentication on your outgoing SMTP server, you can whitelist an e-mail by e-mailing :

 

assp-white@YOURDOMAIN.COM

 

With 1 e-mail address to whitelist per line in the body of the e-mail.

In additition, every e-mail you send will automatically add every receipient to the whitelist.



Example of whitelisting 3 e-mails for a cablan.net address

How to whitelist an entire domain name

To whitelist an entire domain name, contact us with an explanation as to why whitelisting individual e-mail addresses is not sufficient. We will whitelist it for you.

How to disable a particuliar test

ASSP works with several tests, such as Bayesian, PTR, MX/A record and SPF. You may disable a particuliar test by login to our control panel ( yourdomain.com/cpanel)  and accessing the Virus and Spam checking option under "Mail".
