Hello, I found out the following information:
my SPAMD daemon is running under root. But I have in master.cf(postfix configuration file) the following lines:

Postfix master process configuration file. For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#
# ==========================================================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
# ==========================================================================

-o content_filter=spamfilter:dummy

spamfilter unix - n n - - pipe
flags=Rq user=spamfilter argv=/usr/local/bin/spamfilter -f ${sender} -- ${recipient}

Spamfilter is user for spamassassin(spamd)(but for me is strange that spamd is running under root). I configured master.cf according to
h-t-t-p://onetforum.com/fourm/viewtopic.php?p=27]Kalinga's]Kalinga's Community Support Forum • View topic - Integrating Spam Assassin with Postfix(h-t-t-p replace by http)
It is recomended by spamassassin original www pages.


In local.cf I have: bayes_path /home/spamfilter/.spamassassin/bayes.

And now when I send mail(for example at 21:00 oclock) which spamassassin mark like autolearn= spam and I show to the /home/spamfilter/.spamassassin/bayes so I can see that files bayes_tooks nad bayes_seen was modified in 21:00 but their size didnt change? How is it possible - when spamssassin changes the files so they have to increase their size...When I type command sa-learn --dump magic so I can see that in row nspam increase his value +1. This is confirmation that autolearn works.(but the database dont increase his size).

My second problem: I get mail with sign autolearn=ham. I take the mail and I use the following command: sa-learn --spam --file mail (at 21:55 oclock)l. When type sa-learn --dump magic so I can see that nspam was increased +1 its OK. But when I look to the /home/spamfilter/.spamassassin I can see that database file was change but their size didnt change. Its normal???

And the last problem: When I get mail with sign autolearn=ham so I tried type sa-learn --spam --file mail. When I got the same mail so spamassassin mark the mail again autolearn=ham. How is it possible when I learn bayes by hand (sa-learn --spam --file mail) that this mail is spam? I have explicit set in local.cf bayes_min_spam_num 1. This means that for bayes is sufficient one mail for learning(according to me). But it dosesnt work.

Thanks for advise(I need it necessary).




Sorry for my terrible english.
