Yahoo blocking email (Resources Temporarily Unavailable)

Hi

Yahoo have told me (via the feedback form) that our mail server is temporarily 'deprioritized'

This means that the first few times we connect to the mail server, we get a 451: Resources Temporarily Available, pleae try again later' message (after sending the message). We then have to retry and it seems to accept the message just before its due to expire.

I have asked Yahoo what the reason would be, but they only send generic responses. We have rDNS setup, and an SPF but no luck. Anybody had any experience with this?

Here's a conversation:

I have given up with service providers who want to play these sorts of silly little games - especially if they will not give you a straight answer for the reasons for doing so.

If it is just Yahoo who you have a problem with, then look at your email server configuration for the method to route the email through your ISP.

Problem is this is a production webserver, so we dont have an ISP. I'd love to bypass them but I think we need to address the issue
