While I tend to agree that it would be great to be able to block all HTML you can do this today. LISTSERV(tm) has the capability to filter messages any way you want with the "POST_FILTER" exit. We used this for some time (using the unsupported sample POSTFILTER filter) to block all multipart mail messages as well as common uuencoded bodies. I'm sure this code could easily block any HTML types, allow only plain/text, whatever. This feature is documented in the Developer's Guide. Marty
