DKIM, Exchange server
Posted on 2010-09-17
Good day experts.
I have been having a hell of a time trying to get unblocked by Yahoo mail services.
We have 2 domains both direct to our exchange server, PTR records are in place and all seems well, but for what ever reason we can not send mail to yahoo email. I confirmed we have not been compromised in any way. the issue started 10 days ago and i think this is what happened one of my users forwards that a recipient and email then it got added to spam then that same user kept sending here the same email 20 times in the same day because the recipient said she did not get it, (turns out it was in her Junk) so now we are blocked, i have requested to be delisted from Yahoo but all I am getting is automated response.
I have tried everything so now i am looking at DKIM
can some one help me here on how to get this up and running so i can resolve this issue.
