我想使用 seamonkey mail 发送消息，但没有成功。服务器是 redhat 7.6，postfix 为 2:2.10.1-7.el7。Linux 服务器上的防火墙已禁用。
我向你提供以下信息：
我正在检查 /var/log/mailog 并得到如下行：
[root@myserver ~]# tail -f /var/log/maillog

在 /etc/hosts 上我得到：

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

答案1
将这些添加到您的配置中，因为您使用的是 /etc/hosts 而不是 DNS
lmtp_host_lookup = native
smtp_host_lookup = native

感谢您的支持。尽管我成功解决了问题。我会解释的。
为了使它能够通过 seamonkey 邮件发送。我所做的是从其 mysql 数据库的域表上插入行。我的意思是：
insert into insert into domains(domain) values ('e-address.myserver.com');
我有个问题：是否需要执行 postmap /etc/postfix/transport？如果需要，为什么？
