Re: preventing accidental cleartext from getting reflected: If the mail agent blocks cleartext, great, your recipients won't ever be sent cleartext by your reflector. But we can make the problem harder if we care about someone sniffing the careless sender's message. To prevent this, you can either use an online-SSL system, or you can insist that your members set their email crypto plugin to *always encrypt* when sending to your list. If you're actually building an encrypted-only-remailer, may be able to save participants some tedium by having the remailer have one key for the list-submission-address, and resending messages with individual subscribers' key. Otherwise each subscribe must use a feature called "Groups" in PGP's Eudora Plugin 6.x (which they may not have if e.g., they use command line versions) and *each has to maintain a local copy of the membership list*, which defeats the purpose of using a remailer. Actually these functions belong in the listserver (remailer) not the SMTP agent. 1. filter on: list of acceptable substrings such as headers, 'CDR:' tokens, etc.; and/or entropy threshold and/or; recognized digsigs from members of the list 2. decrypt 3. for each list member encrypt msg from previous step and send .......
