SpamSieve not opening automatically

I’ve noticed lately that when I open Mail, Spam Sieve no longer opens automatically. This problem has only started within the past few weeks. How can I get Spam Sieve to return to it’s default behavior?

thanks!

SpamSieve is only supposed to open when new messages arrive that need to be filtered. Is it doing that for you?

For some reason the rule for Spam Sieve was disabled. Not sure why this occurred since I never manually did this.

Anyway, it seems to be back working now. Thanks for your response.
