Comcast announced today they’re blocking outbound port 25 for their residential customers. What does this mean for email marketers? Not much, unless your home connectivity is through Comcast and then you’ll just need to follow Comcast’s directions in order to send mail. What does it mean for email receivers? It means a lot of us will be seeing a lot less spam from infected Windows machines.
DMARC: an authentication framework

A new email industry group was announced this morning. DMARC is a group of industry participants, including large senders, large receivers and relevant intermediaries working on a framework to reduce the harm from phishing.
DMARC is working on a standard to allow senders to publish sending policies and receivers to act on those policies. Currently, senders who want receivers to not deliver unauthenticated email have to negotiate private agreements with the ISPs to make that happen. This is a way to expand the existing programs. Without a published standard, the overhead in managing individual agreements would quickly become prohibitive.
It is an anti-phishing technique built on top of current authentication processes. This is the “next step” in the process and one that most people involved in the authentication process were anticipating and planning for. I’m glad to see so many big players participating.
