David W. Tamkin remarked:

,,, ...Subscribers may post from other addresses without telling you. It may be a better idea to shunt mail from unrecognized addresses to a holding folder that you review with your own eyes.

That seems to be a reasonable approach. My intention was to reduce the extra traffic of bounce messages to illegal addresses and their subsequent non-delivery notices, not so much to avoid having to see the offending messages myself as list maintainer. I'll watch the results for a while. Perhaps I'll get another bright idea. -- Rick DeMattia <rad@nshore.org> The secret of the universe is|^&*||x|NO CARRIER
