PHP 8.0.14, with squirrelmail-1.4.23-6.fc34.20190710.noarch alas on Fedora 35. First I don''t see a F35 RPM. After upgrading Apache works just fine for loading plain HTML pages but webmail gets an internal server error, 500. I enabled debug logging and below is what I see in the SSl error logs with these 2 lines having errors: AH02008: SSL library error 1 in handshake (server OURDOMAIN:443) SSL Library Error:
