Trapping Spam with SpamAssassin

I know next to nothing about working with SpamAssassin other than it is available for my shared server through my C-Panel.

I am on a small network that I am responsible for.

I have the filter set for '++++'

I made the mistake of clicking on an 'unsubscribe' button and now I am flooded with spam. All of them are using an identical template which is

The advertisers name and link

The advertisers catch phrase and link

The advertisers one line pitch and link

A jpg ad with link
Majority of spam is using this same template
The header reads the score as this:
 Content analysis details:   (-1.4 points, 4.0 required)
 
  pts rule name              description
 ---- ---------------------- --------------------------------------------------
 -0.4 RP_MATCHES_RCVD        Envelope sender domain matches handover relay domain
 -1.9 BAYES_00               BODY: Bayes spam probability is 0 to 1%
                             [score: 0.0000]
  0.0 HTML_MESSAGE           BODY: HTML included in message
  0.9 RAZOR2_CHECK           Listed in Razor2 (http://razor.sf.net/)
X-Spam-Flag: NO

Open in new window

The score is lower that most of the newsletters I get from trusted vendors.

Is there a way to stop this?

I can't afford to be too aggressive and start flagging legitimate mail to others on the network, however, as a safety measure I have setup a mailbox to redirect the flagged mail so that I can look it over and deliver it to the proper recipient if need be.

I have been checking the links to see if any of them had a common domain or subdomain to indicate the source, but no luck.

I did notice, however, that everyone has the same physical address in the jpg.

Since it is in a jpg, it's not going to show up on any test. (drat)

All have this same address at the bottom
Which may or may not be legitimate.

A google search lists JTZ Publishing Co, agents for JTZ Group in Trinidad as just one of the tenets. I don't find this company or the shopping center address on any watch lists.

So back to square one

Either this isn't an active EE area, or I'm asking the question in the wrong way. I'll withdraw the question and look elsewhere.
