SPAM FILTERS. Recently a genealogy newsletter recommended a free spam filtering service called 0spam.com. If configured correctly, this spam filter is supposed to work with mailing lists like those at RootsWeb. However, many RootsWeb list administrators have reported problems with list subscribers using this spam filter who do not have the program properly configured to handle list mail. As a result, challenge e-mails are being sent out to everyone who posts to a list to which the person using this filter subscribes. This is unacceptable and users of the misconfigured 0spam.com filter are being removed from the mailing list as they are identified. If you are using this spam filtering program, please check your system configuration carefully to be sure it is properly set to allow list mail without sending out a challenge/response message. Not receiving your mail from RootsWeb mailing lists? This might be your problem.
