I just set up a Postfix/Procmail/SpamAssassin server but I am not convinced that it is really doing much filtering. I have gotten it to recognize the SpamAssassin special Spam code that produces a really high spam metric, but I've also tried sending it sketchy emails with lots of words like "Nigeria" and "viagra cialis" in the body to no avail. Even an email with no subject and no body seems to get through. Clearly either my tactics are not sufficient to raise SpamAssassin's attention or the service is not working.
Is there any way I can send realistic Spam to my server WITHOUT actually trying to sign up for sketchy websites that will send me real Spam? I would like to do it in a controlled way, not by signing up for "free ipad" or anything of the like.
Edit: I've already used the GTUBE with success - it triggered a spam score slightly > 1000. I'm looking to see "real world efficacy" or as close to it as possible w/o compromising security or creating massive headaches.
