Right, but the issue remains: if some forwarders that *you do not control* are failing to implement SRS, you're dead anyway. SPF is bad by design, and DKIM is much much better, as Wietse Venema pointed out. For example, I have a zigo at debian email, which is only a forwarder. I do not control the forwarder at debian.org, and people often send me email to that address. Unfortunately, when someone has SPF fields, the mail never reaches me, since debian doesn't implement SRS. I really doubt that any DAM will want to implement SRS: I'm almost sure that they will tell me that SPF sux because of the above (the forwarder, which might not be doing SPF filtering, and which you don't control, might not support SRS, which leads to issues you will never be able to solve). And I would agree that this fact sux. DKIM doens't suffer from such issues. Cheers, Thomas
