这是我第一次从零开始build立一个服务器，我认为自己是一个新东西的快速和良好的学习者，所以我尽我所能在CENTOS 6中用dovecot设置postfix，所以我得到了我的maillog拒绝的中继访问：

我可以阅读我的电子邮件，但我不能发送电子邮件给任何人以外，任何人都可以快速查看？
默认值没有改变。
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination
你不是从$mynetworks发送。
您没有发送到mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain 。
也许你想要：
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination smtpd_tls_cert_file = /etc/ssl/postfix/cert.crt smtpd_tls_key_file = /etc/ssl/postfix/key.key smtpd_tls_CAfile = /etc/ssl/postfix/chain.crt smtpd_tls_loglevel = 1 smtpd_tls_security_level = may smtpd_tls_auth_only = yes
修改证书值是适当的。
设置sasl在这里描述太可变，但是http://www.postfix.org/SASL_README.html#server_dovecot应该是一个好的开始。
