dovecot - May 2006 - Dovecot 1.0beta7: STARTTLS/SSL not wanting to start

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

Which mail client(s)?

STARTTLS support is broken in Thunderbird, per a recent thread with 
subject 'START + TLS'

Did you figure this out yet? I can't think of a reason why something in
Dovecot's code could cause it. Maybe you had Dovecot 0.99 linked against
a different version of OpenSSL or something?
