1、修改main.cf配置文件，红色部分为需要注释的部分
vim /etc/postfix/main.cf
# 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#
#check_policy_service inet:127.0.0.1:10030
#header_checks = regexp:/etc/postfix/dspam_header_checks
# Content-Filter
#content_filter = smtp-amavis:[127.0.0.1]:10024
#receive_override_options = no_address_mappings
2、修改master.cf配置文件，红色部分为需要注释的部分
vim /etc/postfix/master.cf
