As a few false positives do occur at those levels, so I usually mark spam at 5 and quarantine around 7 to 20.

Hi, > My email server, squirrelmail, has spamassassin already installed. To Squirrelmail isn't your email server, it's a client to an email server like postfix or sendmail. > configure, it says to enter the score above which emails should be > quarantined. Unfortunately nowhere on that page, nor in the SA FAQ, nor in Perhaps it's not as clear as it should be, but you can find it here: http://spamassassin.apache.org/full/3.1.x/doc/Mail_SpamAssassin_Conf.html#scoring_options The default score is 5, before an email is considered spam, but spamassassin itself only does the scoring -- it's up to another program, such as amavisd-new (separate application) or spamd (included with spamassassin) to do something with the email once it has been determined to be spam. You should ask your administrator what the default score is, because while 5 is what most implementations use, it doesn't necessarily mean it is what yours is using. Also, even if it is 5, there may be some false positives (mail inadvertently marked as spam when it shouldn't have been) that raise the score above 5 that you may want to analyze before discarding.

Searched but did not find any info re scores for squirrelmail inbound
My email server, squirrelmail, has spamassassin already installed. To configure, it says to enter the score above which emails should be quarantined. Unfortunately nowhere on that page, nor in the SA FAQ, nor in the SA WIKI, nor in a search of old messages, can I find any mention of what scores are normal to choose. Looking at the scoring system, it seems most flags are worth less than 2 points. But the max is 999! So what is the right range between 1 and 999 for normal usage? And, honestly, why is such basic info missing from the entry-level usage notes and FAQ?

Learning and reporting with spamc in a single step?
Can spamc do this, or must it be forked to "tee" or something. Ideally I'd like to both report and learn in a single step (such as in a pipe from alpine). I note that spamassassin -r also has the option to learn (by default!), but spamc doesn't for some reason. Or if it does, the manpage neglects to mention it. In a perfect world, I'd also be able to choose the "express" or "manual" spamcop methods, which use different reporting addresses, but if I need to run two commands anyway from my .procmailrc, I might as well use spamc for one and spamassassin (with an alternate config file) for the other. -Dan Mahoney -- Dan Mahoney Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---

Hi Giampaolo,
That's an important fact. I have plenty of ham but I think I'll wait
for fresh uncaught spam to properly generate bayes data.

I seem to have this working by running spamd as the user "spamd" and
then in local.cf I used:
bayes_path /home/spamd/.spamassassin/bayes
At least when it looks like spamd is updating those bayes files and
when I run sa-learn, the same files are updated. So it looks like I
have the single database scenario working.
My intention is to run the following manually every once in a while:
# cat ~/LearnAsSpam.sh
#!/bin/sh
sa-learn --no-sync --spam /home/user1/Maildir/.LearnAsSpam/{cur,new}
sa-learn --no-sync --spam /home/user2/Maildir/.LearnAsSpam/{cur,new}
sa-learn --no-sync --spam /home/user3/Maildir/.LearnAsSpam/{cur,new}
sa-learn --sync
rm /home/user1/Maildir/.LearnAsSpam/{cur,new}/*
rm /home/user2/Maildir/.LearnAsSpam/{cur,new}/*
rm /home/user3/Maildir/.LearnAsSpam/{cur,new}/*

I ran sa-update before but I will run it occasionally in the future
and see if the "stock" SA ruleset can do the job before I seek out a
third party ruleset.

Every language has it's niche. Filtering SPAM seems like the ideal
task for the Pathologically Eclectic Rubbish Lister.

Does spamd support ipv6 yet?
I previously asked this question and was told the best answer might be to wait for 3.3. Was there ever support ratified for ipv6 including proper -A ipv6 access lists, and proper ability to listen on both the ipv6 default and the v4 default at the same time, when specifying -i? I'm not sure which bugs to look at to ascertain this. -Dan -- Dan Mahoney Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---

Sorry, I read "spamd", not sa-learn... I use the trick or running sa-learn via su, specifying the user owning the db. Something like: su -s /bin/sh -c '/usr/bin/sa-learn ...' - TheDbOwningUser However, the su option may be unavailable to your IMAP server. If this is the case, instead try specifying the full path to the db via the --dbpath switch, provided db permission are correctly set. Giampaolo

No. You also need to "teach" enough ham and spam tokens to Bayes. By default, you should train bayes with at least 200 ham messages and 200 spam messages. At that point, you should start seeing bayes scoring your messages. > I have LearnAsSpam IMAP folders for everyone to drag spam that get's > through into.

Basic Setup Questions
Hello, I have just setup spamassassin. A lot of spam is getting filtered. But a lot is not. What are the prevailing additional steps for improving filtering? Is using bayes worth it? My default config does not appear to be using bayes. How do I enable it? The documentation simply says "run sa-learn". Does the creation of the bayes db files effectively enable bayes? I have LearnAsSpam IMAP folders for everyone to drag spam that get's through into. How can I run sa-learn so that it builds a /single/ database from all of these folders and so that spamd uses that single database for scoring everyone's mail? Once upon a time I used a third-party set of rules that could be updated once in a while. Is that still around and is it worth it? Mike
