MTA（Mail Transfer Agent ）：邮件传送代理，由「邮件服务器」扮演 MTA 角色，负责完成 MUA(邮件使用代理，即 Outlook
Express 等邮件收发软件)传送信件的请求，将邮件从一个 MTA ( 您的邮件服务器 )传到另一个MTA（对方的邮件服务器）。因此，简单地说，MTA
错误讯息代码，即是由邮局( 邮件服务器 )来函告知您寄信不成功与退信原因。
MTA 错误代码的表现方式如 550 5.1.1 ，由两大部份组成：「SMTP
代码」与「DSN 代码」所组成。以 550 5.1.1为例，550 为 SMTP 代码， 5.1.1为 DSN 代码。SMTP 代码固定为三位数字， DSN
代码固定为由小数点隔开的三个数字。
一. SMTP 代码:
有一组固定的响应代码，表示邮件服务器对于传送邮件要求的响应状况。其中 421、450、451、452、550、551、552、553、554 等 9
组代码表示您要求邮件服务器执行的动作不成功。

看日志，为什么过不去。
日志就告诉：
Jul 11 23:01:56 mail postfix/smtpd[8446]: connect from localhost.localdomain[127.0.0.1]
Jul 11 23:01:57 mail authdaemond: modules=&authmysql&, daemons=5

Jul 11 23:02:14 mail postfix/smtpd[8446]: disconnect from localhost.localdomain[127.0.0.1]
messages里什么都没有。。
抑郁的就这个，错就错了，怕的是什么都不说啊！！！:'(

人家已经说了，SASL认证失败，如果你确定你的用户名的密码没错，那就是你的SASL没有配置好，自己验证一下SASL是否配置好了。
优秀技术经理
密码使用md5加密的时候，记得要echo -n，不换行，不然换行符也加上，肯定是错的。
纠结啊，现在都不知道该查那些东西了，dovecot用的也是sasl他的验证就过去了，没什么问题。我现在怀疑是main。cf哪儿配错了！！！

我也是很长时间没弄过Postfix了，给你一个文档，你照着看下吧。不支持上传txt文件，所以你把后面的.pdf去掉！

按版主文档配置了，依然那样。。。
求解啊，求解啊！！！！
我的mysql和postfix+dovecot等不在同一机器上，
该改的我都改了，不知道还有那部分需要注意，
我的验证方式是sasl库+“courier-authlib” +mysql的验证。。
把perl -e 'use MIME::Base64; print encode_base64(&postmaster\@extmail.org&)'
写成了perl -e 'use MIME::Base64; print encode_base64(&postmaster@extmail.org&)'
导致@字符被定为特殊字符处理了。
@前边应该加\\来屏蔽掉他的特殊含义！！！
谢谢大家的参与。。
尤其是版主！！！
自己解决问题，值得鼓励
谢谢&&。在这里我卡了两天 。
perl -e 'use MIME::Base64; print encode_base64(&postmaster\@&)'&&这里之前没有\ 导致用户名被MD5加密后变了。
postmaster 的密码我自己改过了，不是extmail&&
所以在用户名postmaster后加上\后&&密码改为extmail&&就认证成功了
[root@mail ~]# perl -e 'use MIME::Base64; print encode_base64(&postmaster\@&)'
