Comment 16 for bug 1247366

Evolution has become very very unresponsive since upgrade from 12.04 to 14.04. (I have an old Atom netbook.) And many good mails are classified as spam now (that didn't happen before). And many spam mails are classified as good. I'm trying to correct this, but the manual classification seems not to improve the situation.

After googling today, the reason seems to be that bogofilter is inactive and spamassasin is active. I can confirm this having a look at .spamassasin and .bogofilter files age. This is a bad situation, and complicates everyday work.
