[TriEmbed] yahoo.com "not same domain" security policy sabotaged delivery of list email to yahoo.com addresses

[Jon Wolfe]

<shakes fist yet again at yahoo>

At the same time, they do a better job than I realized in keeping spam out. You wouldn't believe how many Nigerian Princes and will executors for deceased Wall Street bankers have selected anibit.com as their benefactor. 
(Hopefully the very mention of those words doesn't send yahoo into another fit)

List subscribers that use yahoo.com (or, for example, hotmail.com that forwards to yahoo.com) for their email should probably read this and the rest of you are encouraged to skip it as noise.

Late this afternoon John Vaughters posted a reply (with Yahoo mail)
    to Martin Brooke's remark about "luck". (You Yahooers will have to
    consult the email archive msgs with subject "Another College Drop
    out Billionaire Made from his garage".) It appears that when the
    email list server tried to send this msg to other list subscribers
    using yahoo.com it triggered the new, overly clever security policy
    that Yahoo put in place to fight spam. Unfortunately, in addition to
    fighting spam, it hoses the operation of email lists. 

As the list admin, here's part of what I got corresponding to the
    failure to deliver for your particular case, Jon:

(blah blah)

carver_dude (at) hotmail.com SMTP error from remote mail server after end of data: host mx4.hotmail.com [65.55.33.119]: 550 5.7.0 (COL0-MC5-F31) Unfortunately, messages from (50.28.8.76) on behalf of (yahoo.com) could not be delivered due to domain owner policy restrictions. jonjwolfe  (at) yahoo.com SMTP error from remote mail server after end of data: host mta7.am0.Yahoodns.net [66.196.118.37]: 554 5.7.9 Message not accepted for policy reasons.  See http://postmaster.yahoo.com/errors/postmaster-28.html
(much more blah blah)

All direct and indirect yahoo.com users: this episode caused the list server to try over and over again to deliver John's msg until the "bounce" limit was exceeded, at which point your subscription delivery was disabled (i.e. "nomail" got set with a [A] notation [A for administrator/list robot]). BUT I just went into the admin interface and undid that. So all should be well and you should all get future list mail OK until this happens again. Note that when you get this "weird bounce msg" you can simply visit your subscription page and uncheck the "nomail" box to fix this for yourself. The link to the email info page that goes to your subscription details is at the bottom of every list msg, but you'll need the login info provided by the monthly reminder msg.

This is the first time this has happened, so as you can see "most"
    of the time postings from Yahoo users are going through fine.
    Hopefully we'll figure out the pattern.

I got a wierd "excessive bounces" notification from the triembed server. 

Maybe I'll have to create an Anibit email account to use for stuff like this.
