Are You Using SPF Records?
gravyface writes "I've been setting up proper Sender Policy Framework records for all my clients for past year or so, hoping to either maintain or improve their 'reputation' in the email universe. However, there's a lot of IT admins I speak with who either haven't heard of SPF records or haven't bothered setting them up. How many of you are using SPF records for your mail domains? Does it help? How many anti-spam vendors out there use SPF records as part of their 'scorecard'?"
it has cut down tremendously on the spam claiming to be from my domains.
any other benefit I am unaware of.
If I could walk that way I wouldnt need cologne.
I don't use them personally and we have very few customers at my current job that will request them.
I used to work for an anti-spam company and the request would come in from time to time to have SPF checking built into our appliances. As developers, we did see the benefit of it. But at the time, there was the SPF vs SenderID vs Domain Keys battle going on. Who would win out?
As it appears years later, no one really did.
The problem with the technology is adoption rates. Unfortunately, many of these technologies are not being adopted by the masses. I'm not saying its hurting you by having these in place, but it also might not be doing as much good as you think that it is.
Not just to add a 'me too' but I recently removed SPF completely - mostly because other people couldn't get their entries correct, or just completely failed to update it when they add in extra servers. Legitimate messages were hitting our spam folders. Since I can't train our fine worker drones to actually look in their spam, I opted just to remove it. With greylisting and spamassassin its removal hasn't made any noticeable difference aside from the false positives now being delivered properly.
