Yes, I was hoping someone on this mailing list might know. One question for L-Soft though: in the List Owner's Manual at http://www.lsoft.com/manuals/1.8d/owner/appendb.html#keyLanguage it states that: Note that this affects "application/ms-tnef" attachments only-- LISTSERV does not currently strip WINMAIL.DAT attachments. This confuses me, because I thought you said the WINMAIL.DAT file *was* an application/ms-tnef attachment? But if it's not, and it's where the Return-Receipt info that Exchange needs resides, and it's not getting stripped by default, then I would have expected receipts to work without having to set the list to Language= Exchange.
