Again, a post to the list from a Yahoo user was rejected by Yahoo.
And by Comcast and MSN.  Here's the post:

  Haven't read the link, don't need to.  :-)
  I can believe that some people would think of it that way...

And here are the error messages.  (I'm only listing one of each.
I got one such message on behalf of every user on any of those
three ISPs.)

There's no point in my contacting Comcast, MSN, or Yahoo, since I'm
not their customer.  Would those of you who are their customers please
ask them what's going on and how to fix it?  Thanks.

Until this is resolved, would those of you who have both a Yahoo
account and another account please only post from the latter?  Thanks.
