我正在为Dovecot设置邮件解决scheme。 当我尝试telnet localhost 25连接closures。
在日志中看到的错误是：
postfix/smtpd[22958]: initializing the server-side TLS engine postfix/smtpd[22958]: connect from localhost[::1] postfix/smtpd[22958]: fatal: no SASL authentication mechanisms postfix/master[32651]: warning: process /usr/libexec/postfix/smtpd pid 22958 exit status 1 postfix/master[32651]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
该服务器是一个CentOS 7服务器

这是postconf -n的摘录

并从doveconf -n

而对于rpm -qa | grep sasl rpm -qa | grep sasl
cyrus-sasl-md5-2.1.26-17.el7.x86_64 cyrus-sasl-gssapi-2.1.26-17.el7.x86_64 libgsasl-1.8.0-2.el7.x86_64 cyrus-sasl-ldap-2.1.26-17.el7.x86_64 cyrus-sasl-lib-2.1.26-17.el7.x86_64 cyrus-sasl-plain-2.1.26-17.el7.x86_64 cyrus-sasl-sql-2.1.26-17.el7.x86_64 cyrus-sasl-gs2-2.1.26-17.el7.x86_64 cyrus-sasl-2.1.26-17.el7.x86_64 cyrus-sasl-scram-2.1.26-17.el7.x86_64 cyrus-sasl-devel-2.1.26-17.el7.x86_64
和ps ax | grep sasl ps ax | grep sasl ，显示authsasld正在运行？
23280 ? Ss 0:00 /usr/sbin/saslauthd -m /run/saslauthd -a pam 23281 ? S 0:00 /usr/sbin/saslauthd -m /run/saslauthd -a pam 23282 ? S 0:00 /usr/sbin/saslauthd -m /run/saslauthd -a pam 23283 ? S 0:00 /usr/sbin/saslauthd -m /run/saslauthd -a pam 23284 ? S 0:00 /usr/sbin/saslauthd -m /run/saslauthd -a pam
任何人都可以看到我的configuration有什么问题？
1：首先你需要检查服务saslauthd正在运行
2：因为运行在chroot中的postfix需要编辑/etc/sysconfig/saslauthd并将variablesOPTIONS改为
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"
现在在postfix chroot下创buildsaslauthd的目录
mkdir /var/spool/postfix/var/run/saslauthd
3：现在经过这个步骤，你可以重新启动saslauthd服务
