如何检查Postfix是否支持Do​​vecot SASL?

达夫科特指示说:

从版本2.3开始,Postfix通过Dovecot 1.0系列中的Dovecot SASL支持SMTP AUTH。 如果使用从二进制文件(例如.rpm或.deb文件)获得的Postfix,可以通过运行以下命令来检查Postfix是否支持Do​​vecot SASL编译:

postconf -a 

一旦你确认你的Postfix安装支持…. Dovecot SASL

我得到的输出是:

 cyrus dovecot 

那么对某些人来说,这可能是一个小问题,但是如何validationDovecot SASL支持呢? dovecot输出是否意味着它支持Dovecot SASL? 如果不是,应该有什么输出来表示它?

Debian Jessie,Dovecot 2.2.13,Postfix 2.11.3

postconf(1)手册页(您应该阅读)解释:

  -a List the available SASL server plug-in types. The SASL plug-in type is selected with the smtpd_sasl_type configuration parame‐ ter by specifying one of the names listed below. cyrus This server plug-in is available when Postfix is built with Cyrus SASL support. dovecot This server plug-in uses the Dovecot authentication server, and is available when Postfix is built with any form of SASL support. This feature is available with Postfix 2.3 and later.
