Question

所有人，

我有关于postfix及其发送邮件的问题。我已正确设置，并且能够发送并非垃圾邮件的邮件。

但出于某种原因，当我显示邮件的详细信息时（例如，在gmail上），它会显示一个发件人地址： user@mail.domain.com

我希望它成为 user@domain.com 我怎么会这样做？

我的另一个问题是如何加密电子邮件？没有它直接进入垃圾邮件文件夹？

我使用 mailutils 以 squirrelmail 的方式发送邮件无法发送邮件。然而，squirrelmail可以查看邮件。我使用Debian Jessie作为我的服务器

我的后缀主文件：

myhostname = mail.domain.com
mydomain = domain.com
myorigin = $mydomain
mydestination = $myhostname, $mydomain, localhost, localhost.$mydomain
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
relay_domains = $mydestination
