DMARC: Please Be Careful!

(Cross posted from Spam Resource.) Every couple of days, somebody new pops up on the DMARC-Discuss mailing list to ask some question or share an observation.

AOL Updates Spam Filtering

Over on the AOL Postmaster blog, Lili Crowley announced yesterday that AOL has made changes to their spam filtering system. Specifically, more senders may be subject to blocking with CON:B1 errors. AOL’s website explains that CON:B1 errors indicate that an IP address is being  blocked “due to a spike in unfavorable e-mail statistics.” This strongly […]


SMS Spam is Down?

Cloudmark says, yes, SMS gift card spam is down, thanks to recent action taken by the Federal Trade Commission. Read more over on PC World. I’m very glad to see this. I ended up on the list of one of those spammers and they were driving me nuts. Thank goodness for Google Voice’s report spam […]
