Nit: this comment should mention CHLO. I think you can just say:

// If true, it will return as soon as an error is detected while validating
// CHLO.

If you prefer the current comment, add some commas:

// If true, it will return as soon as an error is detected while validating
// client nonce, server nonce, source address token, or server config.
