Mailing list IMAP archive.

[dovecot at ptld.com]

I am trying to use the IMAP mailing list archive described on https://www.dovecot.org/mailing-lists/

Is this feature still functioning? Using Thunderbird i get an error message that the connection was refused.
I don't know if Thunderbird isn't functioning properly (with handling no password) or if the service is down.

My end goal is i want to search the archive for solutions before asking the list.
Is there a browser based option to search the archives?
I didn't see a search option on https://dovecot.org/pipermail/dovecot/
