我正在尝试使用 Postfix、Docecot 和 Roundcube 在 CentOS 上运行 Web 邮件服务器。每当我尝试向服务器发送邮件或发送测试电子邮件时，它都会失败。我可以登录，所以看起来 Dovecot 没问题。
这是我的服务器日志：
Jul 2 14:01:42 phantastyc postfix/smtpd[20154]: warning: SASL: Connect to private/auth failed: No such file or directory
Jul 2 14:01:42 phantastyc postfix/smtpd[20154]: fatal: no SASL authentication mechanisms
Jul 2 14:01:43 phantastyc postfix/master[18459]: warning: process /usr/libexec/postfix/smtpd pid 20154 exit status 1
Jul 2 14:01:43 phantastyc postfix/master[18459]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
当我向服务器发送测试电子邮件时：
Jul 2 14:01:42 phantastyc postfix/smtpd[20154]: connect from mail-ve0-f178.google.com[209.85.128.178]
然后它显示与上面相同的错误。
当我使用 Roundcube 撰写邮件时，它只是挂起，Sending message...过了一会儿SMTP Error (-1): Connection to server failed，日志中又显示相同的消息。
这是我的postconf -n输出：

当我这样做的时候：
[root@phantastyc ~]# ls -l /var/spool/postfix/private/auth
ls: cannot access /var/spool/postfix/private/auth: No such file or directory

这种方法似乎有效，但现在出现了一条新的错误消息：
Jul 3 03:03:14 phantastyc postfix/trivial-rewrite[23348]: fatal: open database /etc/postfix/vmail_domains.db: No such file or directory
Jul 3 03:03:15 phantastyc postfix/master[18459]: warning: process /usr/libexec/postfix/trivial-rewrite pid 23348 exit status 1
Jul 3 03:03:15 phantastyc postfix/master[18459]: warning: /usr/libexec/postfix/trivial-rewrite: bad command startup -- throttling
此外，Google（我发送测试电子邮件的服务器）返回延迟错误，提示与服务器的连接已断开，将继续重试。

使用 修复上述问题后postmap，我遇到了另一个问题。
以下是一些日志记录：
Jul 4 21:51:20 phantastyc postfix/smtpd[13016]: connect from mail-vc0-f171.google.com[209.85.220.171]
Jul 4 21:51:21 phantastyc postfix/trivial-rewrite[13019]: warning: do not list domain phantastyc.tk in BOTH mydestination and virtual_mailbox_domains

不在本地表中？
这是/etc/postfix/vmail_domains：
[email protected] phantastyc.tk/admin
[email protected] phantastyc.tk/bnguyen
[email protected] oa2019.tk/admin
[email protected] oa2019.tk/bnguyen
我还搞砸了什么事？

由于日志说我不能同时使用域名mydestination，所以virtual_mailbox_domains我从字段中删除了它mydestination，现在发送邮件没问题了。 收到的邮件仍然有点不稳定。
Jul 4 22:10:41 phantastyc postfix/smtpd[13160]: connect from mail-vc0-f173.google.com[209.85.220.173]

这让我很害怕：
(delivery failed to mailbox /var/vmail/phantastyc.tk/admin: cannot open file: Is a directory)
那是怎么回事？
这是ls /var/vmail/phantastyc.tk/admin：
cur
dovecot.index.log
dovecot.mailbox.log
dovecot.uidlist
dovecot.uidvalidity
dovecot.uidvalidity.53b3965c
new
subscriptions
tmp
这是/etc/postfix/vmail_domains：

抱歉，我操之过急。我应该先做这件事。简单搜索后发现邮箱目录中缺少一个尾部斜杠。我的邮件服务器现在运行正常。

看起来 dovecot 配置和 postfix 配置不匹配。
在鸽舍配置中（特别是在第服务认证，你只需定义两个套接字 身份验证客户端和授权主控. 添加一个unix_listener包含内容的部分
unix_listener /var/spool/postfix/private/auth {
mode = 0660
# Assuming the default Postfix user and group
user = postfix
group = postfix
}
