Please describe the problem:
When disabling the option to check for spam with the account settings evolution
continues to do so with the consequence that it occasionally crashes or locks
up. Further investigation finds that if the 'Preferences/Mail
Preferences/Junk/Check incoming mail for junk' is enabled it will continue to
check mail for junk even if the option to check for Junk is unchecked in the
local account settings.

This is using the exchange connector.

Steps to reproduce:
1. Create and account
2. Disable junk checking on the account
3. Check mail watching processes for a spamc process


Actual results:


Expected results:
If an account explicitly disables spam checking the global shouldn't override
the specific account options.

Does this happen every time?
Yes
