I've been separately informed by a list member that the "MAIL FROM:<>" is proper protocol for an automated process to be using. I'll investigate why my system is treating it as "bad mail." But, I would still like to know why one of the lsoft.com servers is sending my LISTSERV the same message almost a hundred times a day. /s/ MarkB Mark H Bramhall, CTO, CodeLab Technology Group [log in to unmask] or [log in to unmask] tel: +1-781-213-6917 fax: +1-781-213-6908
