[44net] DMARC

It appears that comcast and yahoo have implemented DMARC mail filtering around the first of the month. This breaks mailing lists such as 44net. As a result, about a dozen people have had their mail from this list bouncing and they've been unsubscribed from the list as a result. This message won't reach them, but if you happen to hear from a former participant in this list who is wondering what happened, you might let them know that their ISP has broken mail filtering software in place that is blocking their participation. - Brian
