Without error messages none of the emails send by me - one of the subscribers - arrive on the mailing list Moderators-nl. Only administrators on the Dutch Wikipedia are subscribed to this list. I'm also subscribed to other Wikimedia mailing lists such as checkuser-l and stewards-l and while it sometimes takes some time usually the emails arrive on the lists. But for some reason this is not the case for Moderators-nl. I asked list administrator Natuur12 to forward the email I send to him, but that didn't work either.
Some details: I use a hotmail.com email address and I tried to send two different emails - about different topics - on 26 November and on 2 December. Up til now both haven't arrived. Others also believe the list is 'broken' somehow. (For the record: the list did work before; the last email was received on 17 October.)
