[Bug 6394] New: FREEMAIL_ENVFROM_END_DIGIT score

https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6394

           Summary: FREEMAIL_ENVFROM_END_DIGIT score
           Product: Spamassassin
           Version: 3.3.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Rules
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: jason@i6ix.com


I recently received a FP report on an e-mail that hit on
FREEMAIL_ENVFROM_END_DIGIT.  This rule has a score of 1.6, which 
seems maybe a little high.  Henrik mentioned the same thing in comment 
185 [1] of Bug 6155 which is closed as resolved/fixed.  The assumption 
was that there probably isn't much ham in the corpora that matches 
addresses like these and therefore the score may be unfairly high.

[1] https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6155#c185

In addition, there are two scores, possibly indicating intent from the author
for a lower score...

20_freemail.cf:score    FREEMAIL_ENVFROM_END_DIGIT  0.1
50_scores.cf:score FREEMAIL_ENVFROM_END_DIGIT 2.602 2.223 1.770 1.553

Just to clarify, I'm running 3.3.1 installed from CPAN.

This bug is still not resolved.

Running 3.3.1 with sa-update running at 4am daily (confirmed updated 
today) shows that the score is declared in 2 files, 20_freemail.cf and 
50_scores.cf

root@athena [/var/lib/spamassassin]# grep -r "FREEMAIL_ENVFROM_END_DIGIT" *
3.003001/updates_spamassassin_org/20_freemail.cf:header   
FREEMAIL_ENVFROM_END_DIGIT  eval:check_freemail_header('EnvelopeFrom', 
'\d@')
3.003001/updates_spamassassin_org/20_freemail.cf:describe 
FREEMAIL_ENVFROM_END_DIGIT  Envelope-from freemail username ends in digit
3.003001/updates_spamassassin_org/20_freemail.cf:score    
FREEMAIL_ENVFROM_END_DIGIT  0.1
3.003001/updates_spamassassin_org/50_scores.cf:score 
FREEMAIL_ENVFROM_END_DIGIT 2.602 2.223 1.770 1.553

This is copied and pasted from Putty.

I think you meant to put this in 50_scores.cf but made the change in 
20_freemail.cf by mistake.

Regards,
Lawrence

If there are rules which are similarly suspect to FPs, then yes you should
open bugs.  :)

Glad to see this is fixed. It was causing some e-mails from Hotmail 
users to be labeled as spam here, and we re-scored it to 0.001 manually.

Perhaps I should get a ticket opened for the other rules we had to do 
this for?

Would have been better to reply in a comment to the bug.

I believe you are incorrect, if you look at the commits, he definitely modified
50_scores.cf.  And the modification shows up in the updated scores when using
trunk / 3.4.0.  I think it's a problem with sa-updates for 3.3.x.

The last update was March 22. Is that the last update you got?

http://svn.apache.org/viewvc/spamassassin/trunk/rulesrc/scores/72_scores.cf?view=log

This is probably a masscheck corpus starvation issue.

John, as I mentioned in Bug 6574, my backups from January 1 to April 13 show no
new sa-updates, except for the update version number.

Probably. I blew away my SA rules and Bayes database back on March 24th, and
the sa-update put rules back in place, but hasn't received a single update
since apparently.

How bad is the corpus?

Odd, I thought Thunderbird has sent the reply to this bug only, and not
elsewhere.

Looking into this further, I have to agree. Several rules have been altered for
3.3, yet my installation has received nothing new for at least a few months.

Sounds like either sa-update is broken or the DNS records for
updates.spamassassin.org are not reporting a new update version (most likely).
