我试图在CentOS上运行Postfix，Docecot和Roundcube上的webmail服务器。 每当我尝试发送邮件或发送testing邮件到我的服务器失败。 我可以login，所以看起来像Dovecot是好的。
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 当我发送testing邮件到我的服务器时：
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。
而且，当我用Roundcube撰写邮件时，它只是在Sending message...挂起Sending message...并在一段时间后说SMTP Error (-1): Connection to server failed ，日志说相同的消息。
这是我的postconf -n输出：

这里是doveconf -n输出：

而当我这样做：
[root@phantastyc ~]# ls -l /var/spool/postfix/private/auth ls: cannot access /var/spool/postfix/private/auth: No such file or directory
它工作，除了现在有一个新的错误信息：
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
另外Google（我发送testing邮件的服务器）返回一个延迟错误，表示与服务器的连接已经中断，并且将继续重试。
在使用postmap解决上面的问题后，我遇到了另一个问题。
这里有一些日志logging：
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 Jul 4 21:51:21 phantastyc postfix/smtpd[13016]: NOQUEUE: reject: RCPT from mail-vc0-f171.google.com[209.85.220.171]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-vc0-f171.google.com> Jul 4 21:51:21 phantastyc postfix/smtpd[13016]: disconnect from mail-vc0-f171.google.com[209.85.220.171]
不在本地表中？
这里是/etc/postfix/vmail_domains ：
[email protected] phantastyc.tk/admin [email protected] phantastyc.tk/bnguyen [email protected] oa2019.tk/admin [email protected] oa2019.tk/bnguyen
还有什么我搞砸了？
由于日志说我无法在mydestination和virtual_mailbox_domains的域名，我从mydestination字段中删除它，现在外发邮件是好的。 传入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] Jul 4 22:10:41 phantastyc postfix/smtpd[13160]: 514F213E0E3A: client=mail-vc0-f173.google.com[209.85.220.173] Jul 4 22:10:41 phantastyc postfix/cleanup[13164]: 514F213E0E3A: message-id=<CADZik+X9uC8QGJZtNoWKk_Aw0bdCP49DUVgdWkhVBCZVOuz3cg@mail.gmail.com> Jul 4 22:10:41 phantastyc postfix/qmgr[13153]: 514F213E0E3A: from=<[email protected]>, size=1930, nrcpt=1 (queue active) Jul 4 22:10:41 phantastyc postfix/virtual[13165]: 514F213E0E3A: to=<[email protected]>, relay=virtual, delay=0.4, delays=0.32/0.01/0/0.06, dsn=4.2.0, status=deferred (delivery failed to mailbox /var/vmail/phantastyc.tk/admin: cannot open file: Is a directory) Jul 4 22:10:41 phantastyc postfix/smtpd[13160]: disconnect from mail-vc0-f173.google.com[209.85.220.173] Jul 4 22:11:08 phantastyc postfix/smtpd[13160]: connect from localhost.localdomain[127.0.0.1] Jul 4 22:11:08 phantastyc postfix/smtpd[13160]: 4292A13E0E3B: client=localhost.localdomain[127.0.0.1], sasl_method=LOGIN, [email protected]
这吓坏了我：
(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
这里是/etc/postfix/vmail_domains ：
[email protected] phantastyc.tk/admin [email protected] phantastyc.tk/bnguyen [email protected] oa2019.tk/admin [email protected] oa2019.tk/bnguyen
对不起，我正在抢先于自己。 我应该先做。 一个简单的search发现在邮箱目录上没有结尾的斜杠。 我的邮件服务器现在工作正常。
看起来像dovecotconfiguration和后缀configuration不匹配。
在dovecotconfiguration中（特别是在服务auth部分中，你只需定义两个套接字auth-client和auth-master 。在内容中添加一个unix_listener部分
unix_listener /var/spool/postfix/private/auth { mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix }
