I may be wrong, but with allowplaintext: 0 in imapd.conf you deny unencrypted connections with plain/login. You then must use TLS/SSL+plain/login or CRAM-MD5/Digest-MD5. If you don't have CRAM-MD5/Digest-MD5 enabled, there ist only encrypted plain/login left. > It didn't work when I specified "SSL/TLS" in Thuderbird it does work > with STARTTLS.
