That's because it's the default, and the only other option besides flock. Most
people don't bother to re-declare the default setting. Instead, most change it
because they know they don't use NFS and want the speed gains of flock.

Very few people use NFS, but SA defaults to nfssafe in order to err on the side
of caution.

That's fine.

You'll only get into trouble if spam.assassin.prefs.conf has a lock_method
declared and local.cf doesn't have a matching one.

It's perfectly fine if it only exists in local.cf, as all SA processes will
parse that.

They over-ride.

For the most part options in SA config files over-ride each other with the
last-parsed file being the winner. The parse order is:

1) pre-init files (/etc/mail/spamassassin/*.pre on most sites. Should only do
things like loadplugins that must be done before the general rules are parsed

2) default rules (/usr/share/spamassassin/*.cf on most sites)

3) site rules (/etc/mail/spamassassin/*.cf on most sites)

4) user_prefs files (~/.spamassassin/user_prefs for normal SA processes,
spam.assassin.prefs.conf for MailScanner's SA instances.)


You can get into trouble with locks if a user_prefs changes it. This is why the
official docs state you can't change it in user_prefs, and SA's spamd actually
enforces this.
