OSXのspamメール対策にはspamassassin があって、マニュアルによれば自動的に学習するが、学習したメールを廃棄しない　となっている。やってられないので　Spamtrainer を導入した。
解凍して、素直にインストールした。
spammail notspammail のアカウントははマニュアル通りに作ってあったから、
まず、Spamtrainer のマニュアルにしたがって、root 権限で、spamtrainer -fを実行。
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 10.4.7 or 10.4.8, 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 created
The existing directory /var/amavisd/.spamassassin has been
backed up to /var/amavis/.spamassassin_04132007-130258
The existing file /etc/amavisd.conf has been
backed up to /etc/amavisd.conf_back_04132007-130258
@local_domains_maps = ( 1 ); was added to amavisd.conf
This ensures that additional domains will get processed
by the content filter as well.
The existing file /etc/local.cf has been
backed up to /private/etc/mail/spamassassin/local.cf_back_04132007-130300
local.cf was fixed
This ensures the settings are correct for your system.
Starting amavisd…
If you use 10.4.7 or 10.4.8, this may produce:
