Yeah. That's similar to what I'm currently doing. Once our deferred queue to Xtra gets too high bump it to the old outbounder and flush the queue. The issue is I want Yahoo to start trusting our new outbounder and each time I use the old one I can't really see it helping the situation.

Interestingly I now see that Yahoo's mx1 now seems to completely trust us and has for days. Whilst mx2 really hates us and defers emails most of the time.

Thanks for all the on and off list replies so far!

Cheers
Dave

We set the new server to use the old server as a smtp fallback relay. Left it like that for a few weeks until we saw traffic drop off on the old server.

Subject: [nznog] Telecom/Xtra/Yahoo accepting mail from new mail servers

Hi

Inspire Net rolled out a new customer outbounding smtp server last Friday. If anyone wishes to add us to any trusted lists then please add the IP address of 203.114.168.20. All user emails from Inspire Net will likely come from that IP from now on.

Since then, we've had many issues getting emails accepted for delivery to Xtra/Yahoo. For long periods of time they will defer all emails, then accept a few, and then go back to deferring all emails.

The help page in question is�http://help.yahoo.com/kb/index?page=content&y=PROD_MAIL_ML&locale=en_US&id=SLN3434&impressions=true�.

The answer seems to be to wait 4 hours. Which we've done. A lot.

I've contacted postmaster@xtra.co.nz about this issue and had no response. For now, to keep our users happy, we're occasionally manually delivering all emails to Xtra via our old, trusted SMTP server, but this is less than ideal. We need our new SMTP server to be trusted.

My questions are:

-Does any one have any advice to give based on past experience on how long this may last, or how to get our smtp server trusted?
-Does anyone from Telecom want to contact me about this issue?

Thanks in advance for any help given.

Cheers
Dave
