No one likes spam, however, there are great solutions they are all available without cost due to the opensource movement. Looking at my own statistics, since 4/1, I've received 5,607 emails, of which 1,177 were forwarded to my inbox, of these 169 were SPAM. All of the 169 could have been eliminated if I chose to use TDMA which whitelists good senders.
So, long story short, quit belly aching and do something about your spam problem.

[TELECOM Digest Editor's Note: But I cannot run a white list here unless I want to turn this Digest/newsgroup into a very exclusive place for _me and my friends_ . I like to get _legitimate_ mail from legitimate users. I do not like the idea of excluding new users just because they have not met some arbitrary standard on the messages I will accept. PAT]
