OK, I've been testing sending emails to my Yahoo Email account from my VPS email account testing the SPAM filters of Yahoo.

I thought I might be able to activate DomainKey and get past the SPAM folder.  Yahoo likes DomainKey.

I've activated "Use DomainKeys spam protection system to sign outgoing e-mail messages" in Mail Settings via Plesk.

So far no luck....Yahoo is junking all my emails... even with this in the Authentication Line of the email header.

         Authentication-Results: mta141.mail.re4.yahoo.com from=conga3.com; domainkeys=pass (ok); from=conga3.com; dkim=neutral (no sig)

SO...my next test is to get DKIM installed, so I can change that "neutral" rating to "pass".  Maybe that, along with DomainKey, will get my emails out of the SPAM folder.

Any ideas?  I've seen several write ups around about QMAIL + DKIM + PLESK...but I thought I'd check here first.
