Recently four long-time subscribers to this list (two of them PLplot
core developers) have been having trouble with being
automatically unsubscribed from the plplot-devel mailing list.
(I am BCCing this note to them in case they are currently unsubscribed).
Typical messages (which I also receive as list admininstrator) are as
follows:
List: Plplot-devel
Member: <username>@yahoo.com
Action: Subscription disabled.
Reason: Excessive or fatal bounces.
It turns out this is a much broader issue than just plplot-devel
un-subscriptions. According to http://ehc.ac/p/forge/site-support/7413/
these problems are caused by recent (April) changes at yahoo.com
regarding dmarc (yet another stupid corporate "anti-spam" measure)
policy. (See also the remark about yahoo configuration of dmarc at
http://en.wikipedia.org/wiki/DMARC.) So far according to the above
site-support URL and additional mailing list discussions pointed to by
that URL there is no good solution to this problem, and so SF has
decided there is nothing they can do except urge users not to use
yahoo.com for subscriptions.
So I am passing that advice along. I know that is not very
satisfactory, but if ISP corporations are careless with their users' desire
to participate in mailing lists, then the only real option for such
users is to vote with their feet.
Note, the problem is not completely confined to yahoo. The above
discussions also mentioned aol, and although two of the subscribers
here so far affected indeed have yahoo subscriptions, one uses
hotmail, and one uses his own private domain where presumably he
has complete control so it may be a matter of an
incorrect dmarc configuration in his case.
However, I notice gmail has not been a problem here and is not
mentioned in discussions. Therefore, there is at least one large
corporate ISP (and, of course, presumably many smaller ISP's) that so
far are not configuring dmarc the anti-list way that yahoo does.
