Noel, thanks for your answers. Last doubt, as far as I understand from the documentation, the milter processing happends in smtpd(8) before the 'smtpd_recipient_restrictions' (cleanup(8)) check. Thus if I keep my current configuration for my new setup, using smtpd_milters and postgrey (under 'smtpd_recipient_restrictions') I'll have the following routing: mail from Internet -> sid-milter -> clamav-milter -> all the smtpd_recipient _restrictions included postgrey, is this correct? I think that this isn't the optimal solution because the milter checks occur before smtpd_recipient_restrictions where a lot of client/envelope/rbl/etc cleanup is done. I'll be checking for viruses from clients that don't even send a proper ehlo, etc, thus consuming cpu resources. Thanks for any comment about this. Regards, LU
