Re: [SLUG] Hotmail bouncing

There was some loose and inaccurate accusation respecting NKS
mailserver's configuration earlier about Paul's reaction
unsubscribing various hotmail subscribers.

As a volunteer, I admin a couple of Open Source package
related mailing lists. I received this earlier today:

Date: Tue, 11 Feb 2003 09:25:51 -0800
From: postmaster@mail.hotmail.com
To: rpm-list-admin@redhat.com

<snip> repeating this for each of the listed people ...

The permissible reply codes are set out at RFC 2821, section
4.2.1 ( http://asg.web.cmu.edu/rfc/rfc2821.html#sec-4.2.1 )

A 50x return is a permanent rejection, for syntatic reasons.
Clearly no change in sending syntax ocurred. see section
4.2.3. Simply -- the hotmail server is non-compliant with the
RFC.

I too simply unsubscribe when I get a bounce series like this,
if the list software has not beat me to it.
