All I did was answer all their questions they had me answer in an email they sent me and waited a few weeks and then they sent me the quote I have above.

No domainkeys at all!

What did you do? I am still getting alot of questions about why Yahoo is blocking them.

It seems more that anything that DomainKeys was or is still broken and returning false “fail” results.

Yes, Yahoo loves me again! No Yahoo emails caught in the spool this morning!

Update: Just got an email from Yahoo:

“We have reviewed the IP information you have provided and made the appropriate changes in our database. As a result, the recent deferrals you have referenced in your report should now be resolved.”

Cross my fingers that the spool doesn’t fill up tomorrow with Yahoo addresses.

In the past day or so I am now seeing a new error message:

“temporarily deferred due to user complaints – 4.16.56.1″

I sent Yahoo another email about this issue but I have not heard back.

No word yet from the SmarterMail people if they will give me the SM5 release.

It appears that about 75% of my emails do make it to Yahoo. Still frustrating knowing that 25% of the Yahoo folks can’t receive email from me.

Chris,

I found out the SmarterMail rel. 5 has domain keys and DKIM built in to it, so I am seeing if I can get that installed first.

Thanks for the help.

If you removed the private key from the MTA did you also remove the public from DNS?

If you left either in DNS then you are coming up as misconfigured and will never pass.

Try just using DK in a test mail and try just DKIM.

Also they will not whitelist you without DomainKeys in place in some form.

I only asked you to remove them to see if the two conflict.

You need to have one in place.

Try one, then the other. Be sure to remove the public key from DNS. If you leave the key in DNS but do not send the private key in the email header you will fail authentication.

You probably know this but I want to check on it first. Also call Crystal Tech, their DNS guys know more about this than both of us.

It appears that my Yahoo test email is giving me false positives.

It appears that I am still having issues getting any mail to Yahoo.
