Beside a lot of other problem installing SL I reached the point of " now it seems to be OK".
BUT starting Mail, SpamSieve(2.7.1) went into Demo mode and requested me to buy a license?!
I’ll checked your site and downloaded 2.7.5. After installing SL told me SpamSieve needs Rosetta, so I added Rosetta.
SpamSieve still still requests the license AND crashes more the 80% of starting attempts.
I checked the “com.c-command.SpamSieve” file and if was of course changed with todays date.
?!!? helpless ?!
