Pessoal, eu tenho várias listas anti spam configuradas no meu postfix, no 
entanto os usuários vem reclamando constantemente que estão recebendo muito 
spam.

 

Eu tenho postfix + mailscanner + spamasssassin + clamav

 

Vocês tem alguma dica de como enrijecer a política?

 

 

Configurações:

 

smtpd_sender_restrictions = check_sender_access 
regexp:/etc/postfix/sender-access, reject_non_fqdn_sender, 
reject_unknown_sender_domain, reject_unauth_pipelining

 

smtpd_recipient_restrictions = reject_non_fqdn_sender, 
reject_unknown_sender_domain, reject_non_fqdn_recipient, 
reject_unknown_recipient_domain, permit_mynetworks, reject_unauth_destination, 
reject_unauth_pipelining, reject_invalid_helo_hostname, 
reject_non_fqdn_helo_hostname, reject_rbl_client zen.spamhaus.org

 

smtpd_data_restrictions = reject_unauth_pipelining

 

smtpd_helo_restrictions = permit_mynetworks, reject_non_fqdn_hostname, 
reject_invalid_hostname, permit

 

Abs,

Juliano
