Hi, I'm looking for a way to autenticate my email users via Dovecot SASL TCP connections from an external nodejs or python script. Dovecot configuration is fine, if I set in postfix smtpd_sasl_path = inet:127.0.0.1:12345 works fine. But if a try via "telnet 127.0.0.1 12345" to chat with SASL in dovecot log found: dovecot: auth: Error: Authentication client not compatible with this server (mixed old and new binaries?) What is the right way to chat with SASL via TCP port?
