Option for notify senders does not work

[Jesus Garrote]

Hi all,

We are running "MailScanner-4.11-1" in one of our servers and all works fine,
except to notify the people who sent us messages containing viruses or
badly-named filenames.

Looking in the " MailScanner.conf " file:

        Notify Senders = yes

But no mail is sent to the mail senders.

Cleaned mails, and correctly-named filenames are sent "ok" to the all
recipients.
Also local "postmaster" receives the notices.

What are we doing wrong ?

Thank you very much.

    Jesus
