Initially when I had to deal with sending to yahoo I would get a mix of mail
dumping into the receivers spam box to downright rejections. Then it moved
completely to rejections. I have exec's that send mail to all the big
providers, usually to lawyers and lobbyists that are either too clueless or
too cheap to have a better mail system. Aol and yahoo at the time just wanted
SPF records and reverse DNS that resolves.
I have thought about DKIM in sending, but so far in using DKIM for receiving
mail with spamassasasin I just get more false negatives with the yahoo spam
because a lot of it actually is through their servers so it gets properly signed.
I initially wanted DKIM to resolve mails from our bank not getting mixed in
with all the phishing attemps. Adding a little bit of negative score helps it
get through, but now maybe I will have to add a meta rule on some common
combinations to catch the yahoo spam.
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
