postfix + dovecot 配置，没有收到邮件

postfix + dovecot 配置，没有收到邮件

我正在尝试在自己的服务器上安装 postfix + dovecot 邮件服务器，但无法接收邮件。我按照此教程操作https://samhobbs.co.uk/2013/12/raspberry-pi-email-server-part-1-postfix（以及查看其他内容）。使用 Thunderbird 时，我可以连接到我的服务器并发送邮件。但收不到传入邮件。

这是我的 postfix main.cf 的样子：

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# TLS parameters
smtpd_tls_cert_file = /etc/ssl/certs/server.crt
smtpd_tls_key_file = /etc/ssl/private/server.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = embe-it.de
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = embe-it.de, h2535210.stratoserver.net, localhost.stratoserver.net, , localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

home_mailbox = Maildir/
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes 
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes

#smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
#smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
#smtpd_client_restrictions = permit_networks, permit_sasl_authenticated, reject_unknown_client_hostname
#smtp_tls_security_level = may
#smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_auth_only = yes

这是 master.cf（用于启用 smtps）：

# of the file, see the master(5) manual page (command: "man 5 master" or

对于 dovecot，我编辑了 10-master.conf：

# ...
service imap-login {
  inet_listener imap {
    port = 143
  }
  inet_listener imaps {
    port = 993
    ssl = yes
  }

  # Number of connections to handle before starting a new process. Typically
  # the only useful values are 0 (unlimited) or 1. 1 is more secure, but 0
  # is faster. <doc/wiki/LoginProcess.txt>
  #service_count = 1

  # Number of processes to always keep waiting for more connections.
  #process_min_avail = 0

  # If you set service_count=0, you probably need to grow this.
  #vsz_limit = $default_vsz_limit
}
# ...

10-身份验证.conf：

# ...
disable_plaintext_auth = no
auth_mechanisms = plain login
# ...

最后在 10-ssl.conf 中启用 ssl（使用默认证书）：

# ...
ssl = required
# ...

我的域名是 Ubuntu 14.04 上的 embe-it.de。我创建了一个名为 marvin 的用户和 Maildir，现在其中包含由 dovecot 创建的文件以及三个目录 cur、new 和 tmp。日志显示了发送的邮件，但没有收到的错误（现在，在我删除它并重新创建一个空文件后，它不再填充）。我测试了使用 telnet 进行连接（本地和远程），成功了。

你有什么建议吗？

通过重新安装和重新配置所有内容解决了这个问题。我不知道到底是什么问题。
