[Dovecot] Problem accessing Dovecot mailing lists via IMAP

[William Blunn]

I recently tried to look at the Dovecot mailing lists through an 
already-configured IMAP profile, which had worked fine in the past.

But it failed saying that the authentication method was not supported.

http://www.dovecot.org/mailinglists.html says:

"You can get access to the IMAP archives by using *dovecot.org* as the 
hostname, *anonymous* as the username and an empty password. It's also 
possible to use ANONYMOUS authentication mechanism if your client 
supports it (few do)."

I noticed that my e-mail client was configured to use the server 
"imap.dovecot.org", so I changed it to "dovecot.org".

But it still complains that the authentication method is not supported.

I am using Thunderbird 3.1 over Windows 7 64-bit.

Thunderbird was configured for "Password, Transmitted insecurely" (and 
this option was not working).

I have tried the other authentication options available in Thunderbird.

"Encrypted password": Does not work; same problem
"Kerberos / GSSAPI": Does not work; same problem
"NTLM": Does not work; same problem

Any ideas?
