Deleting SA headers on ham

[David Baron <d_...@012.net.il>]

Occasionally, I get false positives. I run the sa_learn to mark as ham. The 
spamassassin spam headings remain. Is there a script or optiont that I might 
use to remove them (restore message to original form) ?

 From man sa-learn (SA 2.64):
If the messages you are learning from have already been filtered through 
SpamAssassin, the learner will compensate for this.  In effect, it 
learns what each message would look like if you had run "spamassassin 
-d" over it in advance.

 From man sa-learn (SA 3.1.7):
If the messages you are learning from have already been filtered through 
SpamAssassin, the learner will compensate for this.  In effect, it 
learns what each message would look like if you had run "spamassassin 
-d" over it in advance.

IOW, sa-learn "knows" what headers SpamAssassin adds.

I should point out that it does NOT inherently understand headers added 
by other scanning systems - including those that either call the 
SpamAssassin Perl libraries (Amavis, MIMEDefang), or call spamassassin 
or spamc (qmail-<something>) but add their own headers based on the 
results of the scan.  However, bayes_ignore_header <header name> in your 
main SA config should compensate for that.

Is it necessary to remove SA headers during the learn? I use two
methods arbitrarily;

Method 1 is to extract the original message from the mail archives
which are created before SA does it's thing, so the mail has no SA
headers at all.

Method 2 is to copy the mail from the user backup directory in which
case the mail is as seen by the user - with SA headers.

In both cases I use sa-learn --spam -u <sa user> /path/to/spam

Am I harming my scoring doing it this way?

Kind regards & seasons greetings

Of course not, sa-learn doesn't output a message.  If you're trying to pipe
stuff here, you will want to use a temp file to capture the message, learn it,
then strip the markup away.

Why on earth are there two different functions for the letter d in
spamassassin?

Meaning 

spamassassin -D
spamassassin -d

do or are associate with two different functions/things

Isn't this counterproductive in error or mistake situations?

I changed my ham script to:
nice -n15 sa-learn -L --ham --no-rebuild --single | spamassassin -d

This did not work.

Use 'spamassassin -d' (aka 'spamassassin --remove-markup') to remove
any SA markup in the message.

  spamassassin -d < message-marked-up > message-original

See 'man spamassassin-run' for more information.

  man spamassassin-run
