I have a dedicated server running a popular Uk forums on it. Over the past 3 months I have been having a nightmare with yahoo and btinternet nto accepting mail from us, or sending it to us.
it appears quite a lot of other senders do not now trust out email domain (paypal for example doesnt send notification emails any longer)
I want DKIm implementing with postfix which I run on the server. Centos is version [url removed, login to view] iirc.
I need someone with a strong unix knowledge who is happy to fix this problem and help us get our email clean again. I check daily for blocklists and we have again been put on backscatter for 2 weeks, due to bounced emails I think.
PLease include summary of your skills and what you propose to do.
