Hi, It looks that the spammers found a way to trick DCC and SpamAssassin. They are generating an html e-mails with an invisible words (font color of the text is the same as the bg color). Currently we got "font color="#ffffff" (white) messages only. All words a regular words, not included any spam checks. Is it possible to exclude the "invisible" words from the DCC checking? Thanks, Val P.S. See below for an example of this kind of messages. == Valentin S. Chopov, CC[ND]P Sys/Net Admin SEI Data Inc.
