大家好。

我在debian sarge中使用postfix建立smtp服务器，pop3服务器使用cyrus-pop3，安装完成以后不能使用outlook等mua正常登陆，在/var/log/mail.log中有如下记录：
Jan 20 16:55:19 mail2 cyrus/master[443]: process 1150 exited, status 0
Jan 20 16:55:19 mail2 postfix/smtpd[1147]: connect from unknown[219.239.240.140]
Jan 20 16:55:20 mail2 postfix/smtpd[1147]: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: No such file or directory

Jan 20 16:56:19 mail2 postfix/postfix-script: stopping the Postfix mail system
Jan 20 16:56:19 mail2 postfix/master[1001]: terminating on signal 15
但是/etc/sasldb2这个文件是存在的，并且，权限为666
