Reindl, thanks again for your email, but now I realize that perhaps
you misunderstood my problem. I have got the SSL working with the
config presented in my first post. The problem is that I'm surprised
that Dovecot lets clients establish an SSL connection even when the
client doesn't present a certificate. I don't want clients without a
valid certificate even establish an SSL connection.

I've been using Dovecot 2.1.8 on OpenBSD 5.2 i386 for about a month. It works
great. Dovecot serves IMAPS only,
and I'm using Thunderbird to access my mail.
I configured Dovecot to allow clients that present a valid certificate when
establishing SSL connection. I
configure my Thunderbird for SSL/TLS connection with normal password. It works
fine.
However, with my config anybody can connect to my server without presenting a
certificate
google "dovecot ssl client certificate" leads to
http://wiki.dovecot.org/SSL/DovecotConfiguration
well, this is for dovecot 1.x, but have you tried it?
Client certificate verification/authentication
If you want to require clients to present a valid SSL certificate, you'll need
these settings:
ssl_ca_file = /etc/ssl/ca.pem
ssl_verify_client_cert = yes
auth default {
ssl_require_client_cert = yes
..
}
