OS X 10.10.5 May Need 2.9.21
I am in the Public Beta program for OS X 10.10.5 which was installed (14F19a) by Software Update yesterday, July 31. I was unable to open Mail today until I removed version 2.9.20. I reinstalled it and opted into the 2.9.21 Public Beta and Mail seems to be OK now. This could also have been a glitch in the 10.10.5 beta installation.
I think so, because it doesn’t look like Mac OS X 10.10.5 needs any changes for SpamSieve. If you can’t launch Mail, please see this page.
