我很难让 postfix 发送电子邮件。
这是 mail.log 条目：
Jun 30 18:27:46 vm21 postfix/smtpd[15682]: warning: ::1: address not listed for hostname localhost
Jun 30 18:27:46 vm21 postfix/smtpd[15682]: connect from unknown[::1]
Jun 30 18:27:46 vm21 postfix/smtpd[15682]: NOQUEUE: reject: RCPT from unknown[::1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<momc$
Jun 30 18:27:46 vm21 postfix/smtpd[15682]: lost connection after RCPT from unknown[::1]
Jun 30 18:27:46 vm21 postfix/smtpd[15682]: disconnect from unknown[::1]
/etc/hosts 文件有
::1 localhost ip6-localhost ip6-loopback
这是我的 postconf -n

答案1
“localhost 中未列出地址”消息具有误导性。请使用：
mynetworks = 127.0.0.0/8 [::1]/128
答案2
检查 /etc/hosts 文件。localhost
的 ipv6 地址是否已插入？
该行应如下所示：
::1 localhost ip6-localhost ip6-loopback
如果没有，请添加并重新启动 postfix。尝试再次发送电子邮件。
