auth-plain controls whether the servers offer the plain-text SASL mechanism. Enabled by default. Note that disabling auth-plain doesn't disable all plaintext passwords, since SASL isn't always used. To disable plaintext passwords, use the allow-plaintext-passwords variable above.
SASL authentication is available for IMAP, POP, SMTP, LMTP and SMTP/Submit.
auth-plain is a toggle. Its default value is true:
auth-plain = true
You can see its current value with the command aox show cf auth-plain.
Toggles are written as a single word. Yes, true, on, 1, and enabled all mean that the toggle is enabled, while no, false, off, 0, and disabled unsurprisingly mean disabled. Toggles are case-insensitive.
Spaces are allowed at the start of the line, before and after '=', and after the value. Comments extend from '#' to the end of the line.
