Hi Harald
Thanks very much for your quick reply. Please see my answers inline below
telnet is worthless because AUTH is likely announced *after STARTTLS* http://www.postfix.org/postconf.5.html#smtp_sasl_security_options
right, but when requesting for example mail.wyona.com, then I can see AUTH
depends on the servers configuration
hence I would assume to see it also for the new version of postfix and dovecot, or do I misunderstand something?
yes, you did not read http://www.postfix.org/postconf.5.html#smtp_sasl_security_options
if the server is configured in a way it offers AUTH only over a encrypted channel (recommended) then you need to use STARTTLS before you see the capability and for that telnet is just the wrong tool
