請教關於postfix驗證報錯
OS: redhat as 4.2
Postfix: redhat 自帶的postfix-2.1.5-4.2.RHEL4
Cyrus sasl: redhat 自帶的cyrus-sasl-2.1.19-5.EL4
已完成配置，sasl也啟動了，測試如下：
# telnet system.test 2500
Trying 127.0.0.1...
Connected to system.test (127.0.0.1).
Escape character is '^]'.
220 system.test ESMTP Postfix
EHLO system.test
250-system.test
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH GSSAPI PLAIN CRAM-MD5 DIGEST-MD5 NTLM LOGIN
250 8BITMIME
從以上內容看，postfix應該支持sasl驗證了，驗證機制是:saslauthd，不過我在用foxmail發郵件的時候，報535錯誤，驗證失敗，我使用passwd修改過帳號的密碼，還是報錯，是什麼問題呢？

用戶名密碼的確都是test1，為什麼還是鑒權失敗？？
《解決方案》
已搞定，原來是foxmail不支持PLAIN的驗證方式，我把驗證服務該為：pwcheck_method: auxprop，然後再改其他的配置，就OK了。
