当我从我的Gmail发送testing邮件到我的服务器，我得到这个错误：
致命的：没有SASLauthentication机制
这里是我所有的configuration文件和日志文件，以帮助我们：

这里是版本：
postfix-2.10.1-6.el7.x86_64 dovecot-2.2.10-5.el7.x86_64 CentOS Linux 7.2.1511内核Linux x86.5上的4.8.5-1.el7.elrepo.x86_64
@UPDATE 02
这是我的doveconf -n：
[root@ns1 ~]# doveconf -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 4.8.5-1.el7.elrepo.x86_64 x86_64 CentOS Linux release 7.2.1511 (Core ) auth_mechanisms = plain login disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd }
您的$mydestination不包含您的$mydomain 。 当Postfix收到邮件时，它会查找域名是否在$mydestination ，如果不是，它会尝试对发件人进行身份validation（因为它认为邮件是由客户端提交的，而不是由另一个服务器提供的）。
将$mydomain或由服务器托pipe的域列表添加到$mydestination 。
此外，您的SASLconfiguration似乎中断。 你启动saslauthd ，但configurationPostfix来连接Dovecot进行authentication：
smtpd_sasl_type = dovecot
由于您已经configuration了Dovecot，您可以省略使用saslauthd 。 如果邮件提交失败，请确保dovecot已在postconf -a列出。
