Double blank (from entries created before 1.7f) is internally translated to // which means "all topics" (nothing to do with JCL, this is just the last character in the MIME base64 table). When 1.7f creates an entry, it always supplies something in that field based on the value of "Default-Topics=" or the topics selected by the user. Unfortunately, as you pointed out the default for that keyword is NONE (coded as AA) rather than ALL and this is not what the list owner expects. I will fix this for the next release. Eric
