What is SASL authentication in Postfix?
To address this need, Postfix supports SASL authentication (RFC 4954, formerly RFC 2554).

Once a client is authenticated, a server can give it “same network” privileges.
What does SASL stand for?
Simple Authentication and Security Layer
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols.
Is SASL secure?
SASL provides developers of applications and shared libraries with mechanisms for authentication, data integrity-checking, and encryption. SASL enables the developer to code to a generic API. This approach avoids dependencies on specific mechanisms.
How does SASL authentication work?
SASL uses two important identifiers for users. The authentication ID (authid) is the user ID for authenticating the user. The authentication ID grants the user access to a system. The authorization ID (userid) is used to check whether the user is allowed to use a particular option.
What is SASL username and password?

To ensure that the mail server accepts no mail without TLS encryption, we need to tweak a variable called “ smtpd_enforce_tls “. So to fix the error, our Support Engineers first take a backup of the configuration file.
Where can I find the SASL config file?
Additionally, we ensure that the sasl config file contains no incorrect data. In RedHat servers, the file is at /usr/lib64/sasl2/smtpd.conf and in Debian or Ubuntu servers, it is at /etc/postfix/sasl/smtpd.conf
