[Dovecot] dovecot.procontrol.fi anonymous access fails?

Hi,

just started using dovecot on FreeBSD. Nice and easy to configure :-)

I then wanted to browse the dovecot mailing list, so, according to http://dovecot.procontrol.fi/mailinglists.html:

IMAP archives available from dovecot.procontrol.fi, either use
ANONYMOUS authentication or give anonymous as username and empty
password.

I was using a patched sylpheed that doesn't support ANONYMOUS authentication, so I gave anonymous as username and empty password, but it failed as shown in the following trace:

1 CAPABILITY

• OK dovecot ready.
• CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED AUTH=PLAIN AUTH=ANONYMOUS 1 OK Capability completed. 2 LOGIN anonymous 2 BAD Error in IMAP command received by server. 3 LOGOUT
• BYE Logging out 3 OK Logout completed.

Anyway, I also tried a plain telnet and it failed in the same way. what's wrong?

thanks marco
