I had a chain letter type posting on one of SUVM's lists yesterday. It came out of bit.listserv.novell. It made me wonder how LISTSERV handles the following situation: Sender: NETNEWS@AUVM From: [log in to unmask] If Filter= contains [log in to unmask] will the posting be rejected? Or will the presence of a legitimate address in Sender: allow the posting through? Would listing [log in to unmask] in TRAPIN result in different behaviour? Glenn A.
