把maillog贴出来 检查自己的maillog

★贰℡叁★

建议LZ先使用postconf -a看看你的Postfix是不是已经正常加载了sasl～！再检查一下你的maillog是不是有如下错误提示：
Jul 24 14:58:46 wap postfix/smtpd[15000]: warning: unsupported SASL server implementation: cyrus
Jul 24 14:58:46 wap postfix/smtpd[15000]: fatal: SASL per-process initialization failed
Jul 24 14:58:47 wap postfix/master[14946]: warning: process /usr/libexec/postfix/smtpd pid 15000 exit status 1
Jul 24 14:58:47 wap postfix/master[14946]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

如果是的话～那估计LZ用的是比较新版本的Postfix，比如2.3或者2.4～那就需要重新编译你的Postfix，编译的是需要添加一个参数：-DUSE_CYRUS_SASL

具体内容可以参考如下：

今天把postfix升级到2.3.0 之前2.2.10一直使用很好，当然还是按以前的编译方式，但却发现smtp不正常，察看log显示以下错误

Jul 24 14:58:46 wap postfix/smtpd[15000]: warning: unsupported SASL server implementation: cyrus
Jul 24 14:58:46 wap postfix/smtpd[15000]: fatal: SASL per-process initialization failed
Jul 24 14:58:47 wap postfix/master[14946]: warning: process /usr/libexec/postfix/smtpd pid 15000 exit status 1
Jul 24 14:58:47 wap postfix/master[14946]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

好生觉得奇怪，察看2.3.0的Change log ，找到原因，原来编译的时候必须加一个参数，英文是这么写的

[Incompat 20051220] The Postfix-with-Cyrus-SASL build procedure has
changed. You now need to specify -DUSE_CYRUS_SASL in addition to
-DUSE_SASL_AUTH or else you end up without any Cyrus SASL support.
The error messages are:

    unsupported SASL server implementation: cyrus
    unsupported SASL client implementation: cyrus
