我只是遵循这个优秀的教程build立一个邮政服务器与Postfix / Dovecot /等 。
我通过它，我可以发送电子邮件就好了。 我使用的域名是jonah.name 。 但是，我无法接收来自外部电子邮件或其他内部邮箱的电子邮件。 如果我尝试向其中的用户发送电子邮件，则会收到一封“未送达邮件返回给发件人”的电子邮件，告诉我用户不明 。 这就是/var/log/mail.log ：

日志确认（第18行）用户是“未知的”。 我重新检查了所有连接到MySQL的configuration文件，但是我找不到任何缺陷。 这里是MySQL的虚拟configuration文件：
# /etc/postfix/mysql_virtual_alias_domainaliases_maps.cf user = mail password = **password** hosts = 127.0.0.1 dbname = mail query = SELECT goto FROM alias,alias_domain WHERE alias_domain.alias_domain = '%d' AND alias.address=concat('%u', '@', alias_domain.target_domain) AND alias.active = 1 # /etc/postfix/mysql_virtual_alias_maps.cf user = mail password = **password** hosts = 127.0.0.1 dbname = mail table = alias select_field = goto where_field = address additional_conditions = and active = '1' # /etc/postfix/mysql_virtual_domain_maps.cf user = mail password = **password** hosts = 127.0.0.1 dbname = mail table = domain select_field = domain where_field = domain additional_conditions = and backupmx = '0' and active = '1' # /etc/postfix/mysql_virtual_mailbox_domainaliases_maps.cf user = mail password = **password** hosts = 127.0.0.1 dbname = mail query = SELECT maildir FROM mailbox, alias_domain WHERE alias_domain.alias_domain = '%d' AND mailbox.username=concat('%u', '@', alias_domain.target_domain ) AND mailbox.active = 1 # /etc/postfix/mysql_virtual_mailbox_maps.cf user = mail password = **password** hosts = 127.0.0.1 dbname = mail table = mailbox select_field = CONCAT(domain, '/', local_part) where_field = username additional_conditions = and active = '1'
是不是在上面的日志答案？ “警告：不要在域名myistination和virtual_mailbox_domains中列出域名jonah.name”
编辑：
试试“mydestination = localhost”
“mydestination：通过$ local_transport邮件传递传输传递的域列表。” 即后缀试图find一个真正的用户称为jonah。 根据你的设置，你希望用户jonah是虚拟的，所以jonah.name不能成为我的目标的一部分（我同意，这是棘手的）。
它看起来像发件人是灰名单，如果发件人重试约300秒后应该通过。 您也可以禁用灰名单。
