It's not possible to use plain text authentication with OpenSMTPD. https://www.mail-archive.com/misc@opensmtpd.org/msg04397.html I guess your migration plan has to give OpenSMTPD a different hostname or port and let postfix run till ever device is moved to a TLS config. The question is confusing: PLAIN AUTH is an authentication method which uses plaintext credentials and encodes them in base64 in opposition to other authentication methods relying on challenges. OpenSMTPD supports PLAIN AUTH, what it doesn't support is authentication outside of a TLS channel. So yes, you can use OpenSMTPD with plain authentication BUT you can't use authentication if you do not setup TLS first. Gilles Understood. My old Postfix installation doesn't use TLS. Following Thomas comment I am going to install OpenSMTP and migrate devices to TLS. Thank you very much. P.D: Sorry for my bad English

Re: plain text authentication
Hi, I need to use plain text authentication. I have to migrate an old postfix server that uses this authentication mode. I have a lot of devices configured in this way. I have to plan the migration to TLS, while I want to use OpenSMTPD with plain text authentication. It's possible? It's not possible to use plain text authentication with OpenSMTPD. https://www.mail-archive.com/misc@opensmtpd.org/msg04397.html I guess your migration plan has to give OpenSMTPD a different hostname or port and let postfix run till ever device is moved to a TLS config.
