Thanks for your reply.
Yes, I thought that since I blacklisted the message using SPAM Assassin that the message would not appear in my Quarantine folder. I get SO many SPAM messages a day that it was my hope to drastically reduce the couple of hundred messages that hit my Quarantine folder each day. If I let it go for a few day or a week, my Quarantine folder gets quite large.
If what you say is true, I do not see any functionality in using the Blacklist feature of SPAM Assassin. Conversely, I do see functionality in the Whitelist feature.
It has gotten to the point that email is no longer a reliable form of communication. Two tin cans connected by a string is more reliable. And you can count on a private conversation.
