i use dkim and spf and a slow transport, and use whitelist features by
big mailers if exist. i also noticed that sometimes it takes a few days
if you use a "brand new" ip to deliver out until good reputation for
this ip is accepted, thats all and it works, no need for further
specials ( until general recommends for setting matching ptr records etc )
but in the past yahoo had unknown problems anyway, so i keep monitoring
this, but it always went away after some time, so watching logs is daily
work, but sometimes there is less you can do to fast deliver out
we also send mass mails without problems this way
but you always have to have an eye on it
