My (now prior) e-mail I used on this list was under
GMX (Germany) and I
had major issues trying to get my e-mails to the list.
mail.com is a
U.S.-based sister company to GMX.
A local Linux e-mail listserv I'm subscribed to, uses Mailman and I've
been told by the listserv owner that it doesn't handle e-mail well
from/to Yahoo/AOL addresses.
I had similar issue and found out that it was matter of subscription.
I suggest you unsubscribe and subscribe on
of course it could be the provider, but in my case those mails were
misleading
