Hi David, everyone,

That's OK, but as a recipient, I would find it quite annoying, and I would
set up a rule to discard such notifications anyway.

True.. but as an admin, I don't want to be responsible for that one false positive.


You could construct a new warning message using the MIME::Tools functions,
and call replace_entire_message() inside filter_end to replace the entire
message with your warning message.

        my $msg = MIME::Entity->build(Type => "text/plain",
                                      Encoding => "7bit",
                                      Data => ["first line.\n",
                                               "Second line.\n"
                                              ]);
        replace_entire_message($msg);
        action_change_header("Subject", "Virus warning");

Thank you very much, I was just getting started on googling that one together. One (hopefully) final question, if I may:


replace_entire_message() may only be called from filter_end(), but the virus-scanning gets done in filter_begin(). What would be the proper way to transfer the outcome of the virus-scan between those two functions, or should I just move the virus-scanning to filter_end() too?

Regards, Paul Boven.
