我试图设置我的VPS，所以我可以使用Thunderbird IMAP来pipe理我的邮件。 首先，我安装了postfix并按照本指南创build了一个SSL证书。 然后，我安装了sasl2-bin和courier-imap-ssl并find了这个（德文）指南来设置SASL。 即使是德国人，你仍然可以看到我所做的显示的命令。
在Courier安装之后，Thunderbird终于接受了我的configuration，问我是否会信任我接受的证书。 *但是无法login。只要查看/var/log/mail.info ，每当Thunderbird尝试进行身份validation时，都会logging下面可以find的内容，“admin”是我的用户名。
Nov 19 22:55:19 vps imapd-ssl: chdir Maildir: No such file or directory Nov 19 22:55:19 vps imapd-ssl: admin: No such file or directory
不过，我可以validationPAMvalidation是否有效。
admin@vps:~$ sudo testsaslauthd -f /var/run/saslauthd/mux -u admin -p 'mypassword' 0: OK "Success."
任何线索高度赞赏。
*信使已经创build了自己的证书，所以我甚至不确定手动生成的证书是否真的在某个地方使用。 它仍然被configuration为在/etc/postfix/main.cf使用。
编辑 ：我意外地混淆了赛勒斯与信使。 我实际上已经安装了快递。 Per @masegaloeh的请求，你可以find下面的configuration。

看起来你在postfix存储电子邮件的地方和邮件search电子邮件的地方不匹配。
看看你的postfixconfiguration，很明显，你让postfix将电子邮件存储在默认格式和默认位置， /var/spool/mail/$user与mbox格式 。
在快递中，您使用authpam作为身份validation模块。 因此，预计快递将以maildir格式从/home/$user/Maildirsearch电子邮件。
简单的修复是在postfix存储电子邮件时更改位置和格式。 为此，请在main.cf添加此参数
home_mailbox = Maildir/
它将改变postfix的行为，以maildir格式存储〜/ Maildir /邮件。
