I think Brad is on the right track here, but we can't strip out all non alphanumeric characters because this is common code for all commands sent to the list-request address and valid commands can contain '=', passwords and email addresses. I think the correct approach is to keep popping arguments until you hit a valid command or run out of arguments, but there is an issue here as well, although I think it is already an issue anyway. Here it is. Suppose I send an email to [EMAIL PROTECTED] that has Subject: I want to subscribe to the list and body line subscribe a_paswd nodigest This is a valid subscription email, but if we strip arguments off the subject until we hit a valid command word, we'll try to process the command "subscribe to the list" which will fail and the failure will cause the valid command in the body to be skipped. Of course, the same issue currently exists if the valid command is sent in the body with Subject: subscribe to the list but at least here, it is the users 'fault'. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
