Not sure if this is the place to mention this but the README.POSTFIX file
should be updated since the probe messages depend on this feature as well:
In order to support Mailman's optional VERP delivery, you will
want to disable luser_relay (the default) and you will want to set
recipient_delimiter for extended address semantics. You should
comment out any luser_relay value in your main.cf and just go with
the defaults. Also, add this to your main.cf file:
recipient_delimiter = +
VERP was not enabled in my installation so I paid no attention to this
guideline.
