Probably need SPF, SenderID, DomainKeys and DKIM setup to be safe.

A good quick test is to send an e-mail (via the new smtp server) to: check-auth@verifier.port25.com

This will give you a reply email with a detailed breakdown of what's missing.

Hi,

Do you have DKIM setup on the domain ? And SPF ? If not, try that

Cheers,

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
