Whoa dude - slow down.  Maybe I missed it, but I haven't seen any  
previous questions from you on this matter.  Maybe I missed them too?   
BTW, starting a post to *any* list with "NOBODY EVER ANSWERS QUESTIONS  
TO THIS LIST" is almost guaranteed way to construct a self-fulfilling  
prophesy ;)

In answer to your questions, the same TO/FROM address I'll leave for  
someone else and the remainder of your analysis should be enough.   
Simply add the following to /etc/MailScanner/spamassassin.prefs.conf:

header __SUBJ_STATUS	Subject =~ /status/i
body __BODY_CLK_HERE	/click here/i
rawbody __BODY_HTML	/(?:\<p\>|\<div\>|\<html\>)/i
describe MYSPAM_RULE_1	This message appears to be spam
score MYSPAM_RULE_1		6.0

This isn't perfect, but it should give you a starting point.

For future reference, if you have some web space where you can put a  
RAW, copy of the message other people can have a look at it and  
together we can make some rules to address your specific problem.  In  
future, if you flame everyone on the list with accusations of ignoring  
you, I personally will do exactly that :)  I have been active (for  
various values of active) on this list for several years and always  
found this community attentive, informative and extremely helpful.   
Please be polite and show respect - especially if you expect the same  
in return.
