For some reason Roundcube is no longer able to deliver my emails through Exim when using TLS.
Probably because exim or dovecot got upgraded without me noticing the problem soon enough.
Squirrelmail is able to deliver without any problems, so dovecot/exim in itself are configured well.
I did find a work-around for roundcube, which is basically replacing
$rcmail_config['smtp_server'] = 'localhost';
by
$rcmail_config['smtp_server'] = '';
which makes that the apache mail() function gets used. This workaround works, but the header of the mail shows that the mail is being sent by apache@localhost and no longer by me@localhost. So not really what I want as this appears to bypass the TLS connection to Exim locally on my machine.
The error-message that I get when trying to sent the email with smtp_server set to localhost is:
Feb 23 09:38:56 PulsarX2 exim[8926]: 2008-02-23 09:38:56 dovecot_login authenticator failed for localhost (####) [127.0.0.1]: 435 Unable to authenticate at present: authentication socket connection error

Does anybody have a suggestion how to get this working properly, or is this a known bug??
ps) software:
