Greetings -
I have been looking at Dovecot with a view to migrating us to it from the Washington IMAP server on our Sun systems.
To start our testing we first of all installed the pre-built version of Dovecot from the Blastwave (www.blastwave.org) community supported packaged software site.
This was Dovecot 0.99.10.4 and we successfully got it working in our test environment: at first just with regular IMAP, then with STARTTLS too. For the latter we installed a properly signed certificate and it works fine: mail clients can connect, use STARTTLS and then use the encrypted connection.
I then downloaded the source code for Dovecot 1.0beta7 and built this myself from source, against the OpenSSL 0.9.8 libraries. I configured Dovecot to use the same certificate and key files as had been used for the earlier version we had just tried out.
Whilst 1.0beta7 works fine for regular IMAP it just does not want to start SSL using STARTTLS at all. The error that is getting logged in the syslog file is:
<date etc> ... dovecot: [ID 107833 mail.warning] imap-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [ddd.ddd.ddd.ddd]
I see in the archived for the list archives that this same problem was asked about for 1.0beta3 but without a solution I could see. Could someone offer any insight/help, please?
Cheers, Mike Brudenell
