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 [email protected] <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.
