Great post Titan

, im suprised to see others chatting about such issues giving helpful insight into them. ESP here of all places.
Unforunately for the anti's and larger corporations such as MS Time Warner Aol and others, Sender Policy Framework, Sender ID and such other router level blocking will not stop us for good. As a veteran email marketer myself ive speant and am still spending alot of time researching and getting past these methods put fourth. Anymore these days it is only those who are on top of things that are surviving. Most of us with solutions are keeping quiet for obvious reasons. With that said Im not saying I have 100% solutions past all of whats been implemented nor do i have the answers to future setbacks but im far from giving up.
