With Postfix, the last line of the custom reply starts with "550
5.1.1". Bounce parsers have enough information to decide that the
user does not exist, regardless of the text that follows.
Your issues with your bounce parser due to custom replies from
non-Postfix MTAs are outside the scope of the Postfix mailing list.
