我应该指出,我还没有设置 DNS 记录(dzervas.gr 还没有指向我的新服务器)另外我在 arch linux x86_64 上
编辑:我创建了一个空的 /etc/aliases,然后出现了newaliases
新的问题(在 telnet 中):
rcpt to: [email protected]
550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table
但!:
rcpt to: root@localhost

.
250 2.0.0 Ok: queued as <some-code>
编辑 2:Recipient address rejected: User unknown in local recipient table
通过local_recipient_maps =
在 main.cf 中设置解决了这个问题,但是现在我的邮件[电子邮件保护]排队!它没有像应该的那样进入 /var/mail/vmail/dzervas.gr/dzervas/!
答案1
运行newaliases
。如果 /etc/aliases 不存在,则先创建它,然后运行newaliases
。
也可以更新/添加alias_maps = hash:/etc/aliases
到 /etc/postfix/main.cf 以消除其他警告。
然后再试一次。
(如果您使用 telnet 进行测试,则不需要有效的 DNS)。
第二个问题:首先$myhostname, $mydomain,
从 中删除mydestination
,因为虚拟域不应列在此处。
然后添加(到 main.cf):
virtual_mailbox_domains=dzervas.gr
重新加载 postfix 并重试。
答案2
mynetworks 需要严格的网络范围
就我的情况而言,有一个错误的 IP 范围/etc/postfix/main.cf
。
# Wrong; Temporary lookup failure
mynetworks = 172.16.0.0/8
# OK
mynetworks = 172.16.0.0/12
/var/log/maillog
后来我才注意到其中有一个错误。
10 月 4 日 13:47:54 postfix/smtpd[25056]: 警告:“172.16.0.0/8”中的非空主机地址位,也许您应该改用“172.0.0.0/8”
如果有人通过 google 的热门搜索来到这里Temporary lookup failure
,我想说请仔细检查你的$mynetworks
格式。
答案3
我的看法:
我确实更改了 main.conf,但我忘了重新加载 postfix。
重新加载后它就起作用了。
答案4
就我而言,“临时查找失败”问题的原因是我开始使用聚合酶链反应我的配置中的表:
mydestination = $myhostname,
pcre:/etc/postfix/local-host-patterns,
$mydomain,
localhost.$mydomain,
localhost
事实证明我从未安装过该postfix-pcre
软件包。在 RHEL 风格的发行版中,可以使用以下命令安装
dnf install postfix-pcre
