[Mimedefang] limiting SA's RBL timeouts

[Gary Funck]

As a follow-up to the discussion regarding the fact that sendmail
and spamassassin perform a lot of DNS lookups, one thing we do here
to speed up SA a bit is to tell it to limit the time it waits for
a response from a spam block list lookup.  We place the following
in our local.cf file in SA's rules directory:

# limit RBL checking to max. 5 secs instead of default of 30
rbl_timeout 5

How much this improves things, I don't know.  It was suggested
on the SA mailing list a while ago.

Is there a similar timeout value for sendmail lookups?
