我刚刚关注了这个优秀的教程使用 Postfix/Dovecot/etc 设置邮件服务器。
我成功了，我可以正常发送电子邮件。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，我会收到一封“未送达邮件已退回给发件人”的电子邮件，告诉我用户未知。出现的内容如下/var/log/mail.log：

日志确认（第 18 行）用户为“未知”。我重新检查了所有连接到 MySQL 的配置文件，但没有发现任何缺陷。以下是 MySQL 虚拟配置文件：
# /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'
答案1
上面的日志中没有答案吗？“警告：不要在 mydestination 和 virtual_mailbox_domains 中同时列出域 jonah.name”
编辑 ：
尝试“mydestination = localhost”
“mydestination：通过 $local_transport 邮件传递传输传递的域列表。”例如，postfix 尝试查找名为 jonah 的真实用户。根据您的设置，您希望用户 jonah 是虚拟的，因此 jonah.name 不能是 mydestination 的一部分（我同意，这很棘手）。
答案2
看起来发件人被列入了灰名单，如果发件人在大约 300 秒后重试，则应该会通过。您也可以禁用灰名单。
