Re: [nznog] SPF problems with nznog registration.

15 Dec 2004

      The problem arises because your e-mail hit an alias on my mailserver which
forwarded it to Richard's Computer Science primary address.

There are two issues that arrise because of this.

1) You set an SPF hard failure on your domain, against spf.pobox.com's
recommendation.
2) The Computer Science mailer (not in my control) drops hard failures,
again, against spf.pobox.com's recommendation.

In the middle sits my mail server that doesn't do anything to do with SPF
at all.

There are two things that I can do to fix this:

1) Install SRS on my mailserver (http://spf.pobox.com/srs.html)
2) Remove all aliases that point to CS's mail server, and host the
mailboxes locally.

As this is a production mailserver, I don't want to rush out and do (1)
right now, but I accept that if SPF is to become widespread, I will have
to do this eventually.

So, in the meantime, I'll do (2) and people shouldn't have anymore
problems.

Can you guys please fix your registration/mail system ? and someone
really should be told that bouncing mail based on SPF records alone is a
bad thing [tm] (sending here because I cant seem to mail them directly..)
