Hi David, I probably received the same one you did and here's what the
hits on my system looked like:

Last night I changed the Botnet score to 1.0 and restarted SA however I
see above that it still gave it a '5'. 

describe        BOTNET                  Relay might be a spambot
or virusbot
header          BOTNET                  eval:botnet()
score           BOTNET                  1.0

I also added this line to the Botnet.cf 
(botnet_pass_domains  mailer190173.service.govdelivery\.com)

Maybe I screwed that up?

I don't really run a mail server in the mail server sense of the words.
What I do is I poll all my mail addresses with Fetchmail then run the
incoming mail through Procmail. After tossing the mailing lists
messages to the appropriate imap folders whats left is funneled into SA
