２月初旬からどんどんspam mail の識別率がわるくなってきた。
そこで、threshold を３に下げてみた。
さらに　/etc/mail/spamassassin/local.cf に
whitelist_from #@mike.md.tsukuba.ac.jp *@kiban.md.tsukuba.ac.jp
を書き加えた。つまりmike とkibenからのメールは無条件にspam と判定しないということだ。
Spamtrainer のバージョンが1.8.5 に上がっていたのでアップデートした。でもって；
ここを参考に （2007/4/21 土曜日の記事）
root# /usr/sbin/spamtrainer -f

If necessary, this will create the missing symbolic link in OS X 10.4.x.
It will also fix other configuration issues in the default installation,
which prevent spamassassin from properly working with additional domains.
All files modified by this routine will be first backed up in their
respective directories
Read the ‘Caveats’ chapter in the included documentation for more information.
Would you like to proceed? (yes/no)
yes
Stopping amavisd…
If you use Tiger Server 10.4.7 or higher, this may produce:
‘Workaround Bonjour: Unknown error: 0’.
It is safe to ignore it.
The symbolic link from
/var/amavisd/.spamassassin to /var/clamav/.spamassassin
has been verified and/or fixed
amavisd.conf needed no changes.
local.cf needed no changes.
Starting amavisd…
If you use Tiger Server 10.4.7 or higher, this may produce:
‘Workaround Bonjour: Unknown error: 0’.
It is safe to ignore it.
root# Workaround Bonjour: Unknown error: 0
というわけで、アップデートだから問題なく終了。で次に；
root# /usr/sbin/spamtrainer -i
