With the exception of xemacs-announce, all other XEmacs mailing lists are open to submissions from non-subscribers. Occasionally, an idiot will send SPAM to them. Please check the headers very carefully before complaining to tux.org. I would strongly suggest using a procmail recipe along the lines of (using xemacs-beta as an example). :0 w: * ^Return-Path:.*xemacs-beta(-request)?＠ * ^TOxemacs-(announce|beta)＠ xemacs-beta.spool This has all filtered all SPAM sent to xemacs-beta for me. It drops Bcc'ed mail, but it is very rude to send Bcc'ed mail to mailing lists anyway. Followups to me or Jason or xemacs-beta, please. TUX ORG Abuse Tracing <abuse(a)tux.org&gt; writes:
