第一个错误是因为

在/etc/default/saslauthd配置中

Example for postfix users: "-c -m /var/spool/postfix/var/run/saslauthd"
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd"

这里并不是用于postfix,使用默认的/var/run路径而导致的

后面的提示是因为postfix对于/var/spool/postfix/var/run/saslauthd没有权限

saslauthd usually establishes the UNIX domainsocket in /var/run/saslauthd/ and waits for authenticationrequests. The Postfix SMTP server must have read+execute permissionto this directory or authentication attempts will fail.
