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 -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
