Michael wrote, in part.. > Are there any attachments that listserv will let through... even if > attachments are disabled? Yes. LISTSERV filters only MIME attachments. From the LISTSERV owner's guide: Note also that attachments sent by Microsoft Outlook cannot be blocked by LISTSERV as they do not follow MIME standards (at least not up to and including Outlook 97; this writer has not installed Outlook 2000). Outlook sends attachments as imbedded uuencoded files and does not use the MIME Content-Type: header. cheers, wayne Wayne T.
