Dear Michael,

Thank for your reply.

I would only notify the sender if that is a mail from my network to
the internet.

When a customer would send a mail, they must be authentificate to the smtp.
I check with postfix a perl script that the "from" are correct with
the smtp login, if yes, I give "dounno" to postfix with and I fix a
transport map.

The transport would send the mail to a specific port to another server
who I've a postfix with amavis.
Amavis receive the mail a specific policy and to my policy, i fix the
forward_method and other rules.

I would put into this policy a rule for notify my customer if they
have send a virus and I've block the mail.

I would not notify a sender outside my network.
Mail from the internet to my network go to amavis with another port :)

Sorry for my english.

Bests Regards,
