Hello Everyone, Yesterday, I got a mail loop in one of my lists (please find below). First time I encountered this in LISTSERV. Isn't it that LISTSERV is supposed to trap postings coming from "postmaster" or "root"? Or is the error due to MSExchange on the other end? I have currently set the list to PRIVATE and explicity defined in Filter=Also, postmaster and root. Is this enough? I need to reset back to PUBLIC in a few days inorder to allow postings coming from BBS echoes. Your comments will be highly appreciated. Thanks. Rey M.
