[Dovecot] Max OS X 10.5 Mail + Dovecot

Hi,

People using the new OS X mail client are unable to connect to the unsigned dovecot-mkcert.sh certificate on my Dovecot installations. Turning off SSL fixes the problem. Is there any way to make it work automatically, or do I just have to get the certificates signed? Has anyone figured this one out before?

Thanks,

Chris
