SpamSieve problem with Mail betas

Hi,
if I install a Mail beta version, SpamSive is inactivated when I launch Mail, as are other bundles.
The other bundles can be fixed by adding the UUID of the Mail version.
Spamsive even with the new UUID still gets inactivated.
Anybody knows why?

Thanks
Michele

I don’t recommend modifying Mail plug-ins yourself. It seems like Mail won’t load them if the code signature isn’t right. I recommend signing up for the SpamSieve public beta if you want to use beta versions of Mail.
