[Zope] Zope Mailing List Software is hugely inconsistent!

Hi All, Does anybody know what list software Zope is using?!?!? The headers of messages that I receive from the list are SOOOoooo inconsistent that they have defied my filters again and again! If there's a moderator listening out there, please, do anything you can to rectify this! As I am subscribed to *several* high-volume lists, it's a serious problem when messages from the list continually land in my Inbox, along with my business-related email. Thanks! ------------------------------ -- Jon S. Jaques --------------- -- Systems Administrator ------- -- Network Publications, Inc. -- ------------------------------
