postfix反垃圾邮件设置

增加防止发件人身份伪造的配置：

# smtpd related config

smtpd_recipient_restrictions =

permit_mynetworks,

permit_sasl_authenticated,

# reject_non_fqdn_hostname,

reject_non_fqdn_sender,

reject_non_fqdn_recipient,

reject_unauth_destination,

reject_unauth_pipelining,

reject_invalid_hostname

smtpd_sender_restrictions =

permit_mynetworks,

check_recipient_access hash:/etc/postfix/local_recipient,

permit_sasl_authenticated,

reject_sender_login_mismatch,

reject_authenticated_sender_login_mismatch,

reject_unauthenticated_sender_login_mismatch,

reject_unknown_sender_domain

# SMTP AUTH config here

broken_sasl_auth_clients = yes

smtpd_sasl_auth_enable = yes

smtpd_sasl_security_options = noanonymous

补充：

配置extmail不允许伪造不存在的本地邮件地址发邮件,不允许并仿冒他人邮件地址发送邮件

cd /etc/postfix/

cat >mysql_virtual_sender_maps.cf<

user = extmail

password = extmail

hosts = localhost

dbname = extmail

table = mailbox

select_field = username

where_field = username

additional_conditions = AND active = "1"

EOF

vim main.cf

smtpd_sender_login_maps =

mysql:/etc/postfix/mysql_virtual_sender_maps.cf

smtpd_sender_restrictions =

permit_mynetworks,

reject_sender_login_mismatch,

reject_authenticated_sender_login_mismatch,

reject_unauthenticated_sender_login_mismatch使配置生效
