ezmlm can strip out MIME parts from multipart MIME messages. Some mail clients use ‘multipart/alternative’ to send both plain text and html versions of the same message. On many lists this is considered annoying and wasteful (messages are usually 2-3 times as large). You can have ezmlm remove the html part from such messages by adding the line ‘text/html’ to DIR/mimeremove. If DIR/mimekeep is present, all MIME parts other than are listed there are removed.
