You know, this has been discussed a lot on the list already (search the archive for "X-Mailer"); why reinvent the wheel? Here's the rule I'm using now, based on one that was posted weeks ago. # X-Mailer handling # Note that one person reported FP on "X-Mailer: webmail.delfi.lt" # so we include "." after "^A-Z0-9" header BCS_XMAILERBOGUS X-Mailer =~ /^[a-z][^A-Z0-9.]*$/ describe BCS_XMAILERBOGUS X-Mailer has NO uppercase letters, numbers, dots score BCS_XMAILERBOGUS 2.0 -- Brent J.
