[Mimedefang] auto white lists and lock files

[Aleksandar Milivojevic]

I'm starting to see more and more lines in my log files about failures 
to create lock file for auto white list database that MIMEDefang uses.

Basically, they look something like this:

Nov  1 10:49:57 foobar mimedefang-multiplexor[27632]: Slave 0 stderr: 
unlock: 27632 failed to create lock tmpfile 
/var/spool/MIMEDefang/mimedefang-autowhitelist.lock.foobar.27632 at 
/path/to/SpamAssassin/Locker/UnixNFSSafe.pm line 144.

Nov  1 10:52:24 foobar mimedefang-multiplexor[27632]: Slave 2 stderr: 
lock: 27632 unlink of temp lock 
/var/spool/MIMEDefang/mimedefang-autowhitelist.lock.foobar.27632 failed: 
No such file or directory

As soon as I'm starting to see them, MIMEDefang more or less gets stuck, 
and Sendmail starts rejecting mails with "451 please try again later".

The non-standard stuff I have in config files is:
MX_EMBED_PERL yes
MX_REQUESTS 10
MX_IDLE 15

In sa-mimedefang.ca:
auto_whitelist_path        /var/spool/MIMEDefang/mimedefang-autowhitelist

And in mimedefang-filter enabled standard initialization stuff for auto 
white lists as distributed in stock mimedefang-filter.
