Just a quick note that the SARE whitelist rules file has been updated. Documentation available at http://www.rulesemporium.com/rules.htm
The purpose of this rules file is to use the whitelist_from_rcvd to avoid false positives for services that we know do not send out spam. It's suitable for use by any and all systems. Because it uses the whitelist_from_rcvd directive, it can also be used in any individual user's user_prefs file. Contributions of additional whitelist entries are more than welcome. Likewise, if you should happen to find any spam flagged by any of these entries, please send that spam to me so the entry can be removed or fixed. Bob Menschel
