Hello,

In spite of:

ssl = no auth_allow_cleartext = yes

..in a telnet session, I get:

• OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ STARTTLS LOGINDISABLED AUTH=GSSAPI AUTH=CRAM-MD5] Dovecot (Debian) ready. a1 login ln@zample.com <super-secret>
• BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. a1 NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections.

I need to see the network traffic to troubleshoot the way Outlook 2019 handles IMAP folders.
