SA Headers not on Ham

[Mosenior Moses <mo...@tvcnet.com>]

Hello,

 We are running spamassassin with qmail/procmail. Spamassassin Version 3.0.1 on Fedora Core 2. 
The problem that I'm seeing is that Ham messages are coming through with out having the SA headers
being added to them. What's interesting is that messages are being filtered even still, as we have a spam mailbox
and I can see recently filtered spam in it. I've done quite a bit of searching around (google of course) and haven't been able 
to determine where the failure is occuring. Is there a configuration I might be missing somewhere?

Thanks,

Excellent, 

 Thanks a lot, I'll look into this.

Agreed, SpamAssassin will always add at least one header to every email 
(X-Spam-Checker-Version).

You have to edit the code directly to prevent it from adding that header, 
there's no config option to prevent it (even clear_headers won't remove it).

So it's almost certainly some kind of glue script that is deciding to use the 
original email if SA doesn't tag it as spam. I've seen several glue scripts that 
do this, some do it intentionally and some do it by accident due to return codes 
causing the MTA to recover it.

Is the mail being filtered correctly, and you are seeing SA headers on spam,
but not on ham?  Or do you also have reason to believe that the mail isn't
being filtered correctly?

Some glue agents do their own version of SA headers, and may not feel the
need to install headers on ham.  Qmail may be one of the things that does
this, I don't know.  But I suspect this is what you are seeing.
