The most spam-related issues with my legit outgoing email I had were
with Yahoo ...
IIRC from my tests which drove me insane, Yahoo seemed to check if the
From header has matching words as the From envelope (note that these
two are not one and the same) and also does similar check on the
Return-Path header. It was extremely hard to send email on-behalf-of
style. Adding Reply-To was making it worse IIRC. They also don't explain
the checks they are doing and it's close to impossible to reach them to
inquire about this in order to adjust your setup.
I just gave up on Yahoo in the end. Not that I adore Google, but I had
far less trouble with Gmail.
Exim does not directly support DomainKeys (it does DKIM) but Yahoo
checks both. There seems to be nothing wrong with your DKIM setup.
@Lena: Blacklisting entire IP blocks at first spam is a bit harsh ... or
maybe Romania has a special place in your heart.
