Train as... actions double number of selected messages

I had to do a complete clean install of Yosemite (meaning erase and reinstall every app). Now SpamSieve 2.9.17 attacks two emails for every email selected. Say I choose a single spam email in my inbox and invoke “Train as Spam,” it marks and moves the selected message and the one following it. Same goes for “Train as Good.” If I select 4 emails, 8 are affected.

Best wishes,

Steve

Are you using Apple Mail? If so, please turn off the faster Apple Mail training.

Thanks, Michael. That seems to have done the trick.

Best wishes,

Steve

Had to turn it off again?
Today I attempted to train as good, which moved an extra email into my inbox. I disabled the speed-up preference again and behavior has returned to expected.

Odd that the preference would reset.

Best,

Steve
