Thanks for the answers, i'm testing the implementation of a modest server, i
have only 15xx accounts near 2000, it's only one domain, i have a
centralized OpenLDAP server where my mail authenticates, i'm using
cyrus-sasl, using submission port to send emails and 25 port to receveive
mail, set smtpd_client_restrictions to require that server sending mail to
my users to have reverse address on dns server, and on submssion port
require sasl authentications between others restrictions to improve some
security and minimize SPAM, my problem starts when i set header_checks to
hold messages for clamav scan, so my mail server stop to send messages, i'll
modify the regexp to hold only incoming mesages that doesn't go to my own
users.
Later i'll search about amavisd-new.
Thanks again and i accept all sugestions
