postfix配置smtp 认证错误[已解决]

neplusultra

采用postfix+cyrus sasl 进行smtp认证，总是没办法运作起来。

在/var/log/mail/errors中提示：postfix/smtpd[10881]: fatal: no SASL authentication mechanisms

main.cf 内容如下：
#================================================

smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients= yes
smtp_sasl_auth_enable = yes

#把下面这一行注释以后postfix收发邮件正常，但是smtp认证就没了
smtpd_sasl_auth_enable = yes

#=====================end of main.cf

# /usr/lib/sasl2/smtpd.conf内容：

看了本版面的所有文章，也在google上搜索了很久，一直不得其解；
希望哪位高手能帮我一下！！谢谢

最终还得靠自己

从log看就是缺了验证算法机制，估计是sasl某个库没装上。（我用MDK10.1，rpm包和source均缺少这个包）。

去光盘search一下，看到libsasl2-plug的统统装上～
ok，test again：

[biabia@master biabia]$ telnet localhost 25
Trying 127.0.0.1...
Connected to master.mydomain.com (127.0.0.1).
Escape character is '^]'.
220 mydomain.com ESMTP Postfix
ehlo
501 Syntax: EHLO hostname
ehlo localhost
250-mail.mydomain.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH GSSAPI CRAM-MD5 DIGEST-MD5 LOGIN PLAIN NTLM SRP OTP
250-AUTH=GSSAPI CRAM-MD5 DIGEST-MD5 LOGIN PLAIN NTLM SRP OTP
250 8BITMIME

基本上smtp认证就ok了

parset

楼主,这样行不??
我也出现了

1. 250-AUTH GSSAPI CRAM-MD5 DIGEST-MD5 LOGIN PLAIN NTLM SRP OTP
   
2. 250-AUTH=GSSAPI CRAM-MD5 DIGEST-MD5 LOGIN PLAIN NTLM SRP OTP

但是,没有办法登陆,提示密码错误!!请指教
