[MlMt] Suddenly SpamSieve not processing new mail

[Ken Pope]

Have been using MM Version 1.13.2 (5673) & Big Sur 11.1 on my MacBook 
Pro (156-inch, 2018) with SpamSieve, which worked wonderfully.  However 
late yesterday SpamSieve (version 2.9.42) stopped processing new mail.  
Junk mail pours into my inbox and none of the new mail has a spam score.

I’ve made sure SpamSieve is checked in MM Security & that it has whole 
disk access.  Have tried turning everything off & on repeatedly, but 
doesn’t help.

Any ideas about how I might fix this?

Thanks as always for your help.

Ken
