Sorry I have to disagree with 1. there, I used their wizard to setup my domains and every once and a while I get my mail rejected anyway. From the site for ~all: "SPF queries that do not match any other mechanism will return "softfail". Messages that are not sent from an approved server should still be accepted but may be subjected to greater scrutiny." People who drop/reject mail based on spf records make kittens cry. But I have ranted about that already. Daniel Many people would sooner die than think. In fact they do. Bertrand Russell --Quoted in Antony Flew's Thinking About Thinking Jamie Curtis wrote:

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..)
