Timeouts

Due to recent "unreliable"  performance of the RBL's used by both
MailScanner and SpamAssassin, I have improved the timeout code for both of
these functions. There are an additional 2 configuration variables in the
mailscanner.conf file, one for "Spam List" entries and one for
SpamAssassin. If there are more than the given number of *consecutive*
timeouts with any particular "Spam List" entry, or with SpamAssassin, then
that function is disabled until the next time MailScanner restarts itself
(within 4 hours by default).

This will mean that if one of the RBL's becomes unreachable, MailScanner
won't slow to a crawl due to all the timeouts. But temporary problems
reaching them will be ignored, only prolonged outages will have any effect.

The default value for each of these configuration variables is 20. To
disable the protection, set the value to 0.

This will be in the next release, along with a whole host of other stuff
I've been working on...
