Hi, Hope there's someone out there that can help on this. I am trying to use pcre header_checks to filter a great deal of email going to one user on my mail server. I tried reading the man pcre_table 5 docs and the description is a little vague but I came up with this: if /^X-Original-To:.*user@/ !/^From:.*([email protected][email protected] endif It doesn't seem to work. I know I can do this in the .procmailrc file, but the mail to this specific user is so huge that I would rather reject everyone that is not listed as a friend right up front. Fortunately there aren't too many friends 10 to be accurate with no need to grow the list. Would appreciate some direction there.
