[vps-mail] Does spamassassin look at its own headers and rewritten subjects?

[SikaSpam <sikaspam@xxxxxxxxxxx>]

I have accounts on several servers, one of which gets a 
huge amount of spam. After dealing with the suspects of 
the worst server, I've been moving the messages over to 
another and using sa-learn on it. However, most of the 
messages have already been identified as spam (subject 
rewritten) and all have sa headers and scores.

Running sa-learn appears to work (messages concerning 
success in learning look right) but I wonder if I'm 
teaching the dog useless tricks?

I seem to remember sa ignoring its own markup, but can 
someone confirm? Or am I teaching to look for 
***SPAM*** in the subject (absurd.)

thx
