Headers screwing up SA?

[Owen B. Mehegan]

I'm using postfix and cyrus-imapd on my server, and I have spamassassin 
running using spamd. In spite of some aggressive third-party rule sets, 
RBLs, and other measures, I still get 10-20 spam messages per day on my 
personal email account. It seems like SA should be better at catching 
some of this stuff, which seems to obviously be spam. One thing I 
noticed when looking at the headers of a spam message is, the initial 
From path is "[EMAIL PROTECTED]," which is the name of my server. I'm 
wondering if this is preventing messages from getting hits in things 
like Razor and other RBLs. Here's the complete headers from one such 
message:

If it turns out that this _is_ causing problems for SA, here are the 
relavent lines (I think) from my postfix configs that I use to deliver 
mail into the cyrus-imap mailboxes. From main.cf:

mailbox_transport = cyrus
From master.cf:
# In order to use the "cyrus" message transport below, configure it
# in main.cf as the mailbox_transport.
cyrus     unix  -       n       n       -       -       pipe
 flags=R user=cyrus argv=/usr/sbin/cyrdeliver -e -m ${extension} ${user}
Thanks in advance,
