Mellis,
So of the users of the Benelux mailing list are using gmail. We have experienced that we always have to rewrite the 'To' field to benelux at arduino dot cc or else a reply will be send only to the originator of the mail you reply to and not the the members of the list.
Do you know if there is a setting in the mailing list that can take care of this?
Thanks in advance!
Jan-Dirk
