So, is that what the morons tried to login with (I have a few others
that using your snippet decode to "Username:" (VXNlcm5hbWU6), they are
trying to login with a base64 encode of "Usernae:" or "Password:"?
No, Postfix is logging the stage of an authentication failure in the
SASL LOGIN mechanism. It would be unwise to routinely log the wrong
credentials used by people who typo a username or password or by bots
that have a list of username+password combinations acquired elsewhere.
