RE: These are getting through SA...
The problem is that Botnet uses Net::DNS::Resolver's default retry and
timeout values, which are way too high.
Spamassassin's DnsResolver.pm uses these values:
export RES_OPTIONS=3D"udp_timeout:3 tcp_timeout:3 retrans:0 retry:1"
before invoking spamassassin and see what happens.
The proper solution would be to fix Botnet.pm to use sensible values for
these parameters instead of the defaults.

Mark, thanks for the patches. However, even with both Dns.pm patches=20
applied, unless I set "rbl_timeout" to a high enough time interval, SA=20
still misses the URIBL test results in the sample messages I posted in=20
For example, if I set "rbl_timeout 15", I get no URIBL hit results. =20
However, if I set "rbl_timeout 60", I do get URIBL hit results. This is
because the 60 interval is long enough for Botnet's (in this case) RDNS=20
test to timeout before the "rbl_timeout" interval.
