Or so I thought: I just tested to see that things were in fact encrypted and unencrypted connection was refused, works fine for Postfix but Cyrus-IMAP accepts unencrypted connections _and_ authentication even though I have set the following in imapd.conf allowplaintext: yes allowplainwithouttls: no How do I force the use of TLS for Cyrus-IMAP? Also: Postfix allows hiding authentication mechanisms unless TLS is invoked (so in clear text, capabilities just show STARTTLS), while Cyrus-IMAP announces everything. Is there anyway to be more strict with the cyrus in respect of what it announces?
