Rigging up Eudora

Go to Tools->Filters (you need a recent EudoraLite).

For each address you have, make a rule:

if To: has "you@your-host"
or Cc: has "you@your-host"
then SkipRest
replacing you@your-host with your own address and the various list submission addresses. Then make a rule saying:
if Subject: has ""
then Transfer to ProbablySpam
All these rules should be the LAST in your rule list, as the SkipRest directive will disable anything following. Of course, if you already have rules like:
if To: has "sydride@cskk.ezoshosting.com"
then Transfer to SydRide
then you don't need the corresponding:
if To: has "sydride@cskk.ezoshosting.com"
or Cc: has "sydride@cskk.ezoshosting.com"
then SkipRest
since that list is already catered for.
