Thank you, Marc. We created our own CA and certificates just fine. The problem is that SSL does not seem to like them giving the error I mentioned in the previous message: dovecot: imap-login: Error: SSL: Stacked error: error:04075070:rsa routines:RSA_sign:digest too big for rsa key What would an SSL+Dovecot expert do if this error was encountered? A 1024 bit key works just fine but we have to stick to 256.
