I don't personally think we're all in trouble. I think if Yahoo sticks by this, I think mailing list managers can choose to roll with it by modifying what they put into the from address when distributing posts, or they can try to convince subscribers to move away from Yahoo. I've certainly had to deal with a scenario similar to the latter in the past; when a certain blacklist operator went off the rails and spite listed all of my employer, I did have some success convincing subscribers to change to an email provider that didn't use that DNSBL, but it was a lot of work for little value. If I were dealing with this specific issue today, I'd probably just hack my MLM to do what I needed it to do, and maybe even look at coordinating with others to see about broader updates to how various MLM software packages work. I know you won't agree with this, but I wanted to point out that there's another point of view here. I guess I've worked at an ESP long enough to know that when you're not the big dog, sometimes you have to roll with what the big dog does, and just deal with it. Yahoo says I have to do X for what I want to work for their subscribers, so I do it. Regards, Al Iverson -- Al Iverson | Chicago, IL | (312) 725-0130 Twitter: @aliverson / www.spamresource.com
