I just set up all lists so that the following MIME types are removed, and if a message contains nothing else, it will be rejected:
application/excel application/rtf application/msword application/ms-tnef text/html text/rtf text/enriched text/x-vcard application/activemessage application/andrew-inset application/applefile application/atomicmail application/dca-rft application/dec-dx application/mac-binhex40 application/mac-compactpro application/macwriteii application/news-message-id application/news-transmission application/octet-stream application/oda application/powerpoint application/remote-printing application/slate application/wita application/wordperfect5.1 application/x-bcpio application/x-cdlink application/x-cpio application/x-csh application/x-director application/x-hdf application/x-httpd-cgi application/x-koan application/x-mif application/x-netcdf application/x-stuffit application/x-sv4cpio application/x-sv4crc application/x-tcl application/x-texinfo application/x-troff application/x-troff-man application/x-troff-me application/x-troff-ms application/x-ustar application/x-wais-source audio/basic audio/mpeg audio/x-aiff audio/x-pn-realaudio audio/x-pn-realaudio audio/x-pn-realaudio-plugin audio/x-realaudio audio/x-wav image/ief image/tiff image/x-cmu-raster image/x-portable-anymap image/x-portable-bitmap image/x-portable-graymap image/x-portable-pixmap image/x-rgb image/x-xbitmap image/x-xpixmap image/x-xwindowdump text/x-sgml video/mpeg video/quicktime video/x-msvideo video/x-sgi-movie x-conference/x-cooltalk x-world/x-vrml There is also a possibility that a message containing these kinds of attachments are simply rejected. Which option is better (I think the latter). Also, I think it is a good idea to pose an upper limit on message size. What should it be? Is 30,000 bytes good on all lists, but 300,000 on the devel list? Mate
