Are any of you admins out there running SPF, or something similar?
This question is too hard for me. What is "running SPF"? I have these top secret records in my DNS zone file. keithdiane.us. IN MX 10 dsl.keithdiane.us. keithdiane.us. IN TXT "v=spf1 mx include:speakeasy.net ~all" (Don't tell anybody.) And I send all my mail through speakeasy, by which I mean that the SMTP server at keithdiane.us forwards through there as a "smart host". I don't use Speakeasy web mail, but if I don't forward through Speakeasy, too much mail gets rejected out of hand, just because it comes from a dsl line. (I think. (It's been a while since I tried it, and you never know exactly why you have been rejected.)) On the other hand, when a host sends mail _to_ my server, it does not check its DNS for SPF at all.
How well does it work for you?
Compared to what? I'm not sure how it works, because I've really never done it any other way. I do know that spam is way out of hand. I get over 100 a day of total stupid stink'n spam. (This does not count mailing lists that I am subscribed to that I do not actualy read; just really stupid crap in Russian, repetitious attempts to sell stuff I had better not mention for fear of falling into the WPI filter, usw) It's almost to the point where I might do something . . . soon.
