Just a bump, still have the problem, why would dovecot support sslv2 for pop, but not for imap, when it's configured to not support sslv2 at all?

I don't know why your nmap run would have shown only one of them supporting SSLv2, it should have shown both. And that's because I initialize OpenSSL with:

ctx->ctx = ssl_ctx = SSL_CTX_new(SSLv23_server_method());

So I guess what happens is that OpenSSL advertises that it supports SSLv2. But then the ssl_cipher_list's !SSLv2 doesn't let the SSLv2 handshake actually go through. So it's not really possible to use SSLv2. You can verify this with:

openssl s_client -ssl2 -connect localhost:995

Anyway.. I guess I should do something about this. Not really sure what, though.
