Hi and thanks - i currently dont have the option for creating
spam/notspam mail accounts - and the count of spam being let through is
now starting become a huge issue - heaps of spamm is not being trapped,
or the reason Nathan pointed out above - Nathan, have you found some
type of fix? I am no guru at this and dont want to have a long list of
SA custom rules i dont know a lot about. Are these the only 2 options i
have? or delete or stop using bayes?
