我想设置 nullmailer 将邮件中继到我的提供商的 SMTP。
由于提供商会丢弃发件人域和用户登录名不匹配的电子邮件，因此我曾经/etc/nullmailer/allmailfrom匹配登录名/etc/nullmailer/remotes并且它有效，我可以将电子邮件发送到完全合格的地址。
我还曾经/etc/nullmailer/adminaddr将所有本地电子邮件重定向[user]@localhost到[email protected].这是因为根据man nullmailer-queue
adminaddr If this file is not empty, all recipients to users at either "localhost" (the literal string) or the canon‐ ical host name (from /etc/mailname ) are remapped to this address. This is provided to allow local daemons to be able to send email to "somebody@localhost" and have it go somewhere sensible instead of being bounced by your relay host. To send to multiple addresses, put them all on one line separated by a comma.
现在我想附加myowndomain.net到通用用户名 ( mail any_username)。根据man nullmailer-inject，
defaultdomain The content of this file is appended to any host name that does not contain a period (except localhost), including defaulthost and idhost. Defaults to the value of the /etc/mailname system file, if it exists, otherwise the literal name defauldomain. defaulthost The content of this file is appended to any address that is missing a host name. Defaults to the value of the /etc/mailname system file, if it exists, otherwise the literal name defaulthost.
据我了解，我应该使用，/etc/nullmailer/defaulthost因为我正在向缺少主机名的地址发送电子邮件。所以我就放在那里myowndomain.net。
但是，nullmailer 仍然附加@hostname.myprovider.net，导致电子邮件被 SMTP 中继主机丢弃：所述域不存在。
如何配置 nullmailer 以仅添加@myprovider.net而不是@hostname.myprovider.net添加到缺少主机名的地址？
