email - GNU 使用电子邮件从同一服务器发送多个外发帐户，无需 imap

Question

我使用 GNU 和多个电子邮件地址，包括根据邮件上的 FROM 更改传出 SMTP。到目前为止，一切都很好。但是，现在我在同一台服务器上有多个帐户，所以通常的 .authinfo 对我不起作用。似乎答案应该类似于 http://www.cataclysmicmutation.com/2010/11/multiple-gmail-accounts-in-gnus/
但我没有使用 gmail，也没有使用 imap。我正在使用 SMTP 和 SSL。我该如何扩展该解决方案？ (另外:我正在使用 gnus-posting-styles 来帮助发送具有适本地址的邮件，这是值得的)

以下是我的 .gnus 的相关部分。请注意，我正在尝试使 webdev@[ME].com 正常工作，这是对 [ME]@[ME].com(都是同一服务器)的补充。我在这里和我的 authinfo 中需要什么才能完成这项工作？

解决方案

我正在寻找的答案在下面。为完整起见，我将使用我的/etc/host 文件、.authinfo 和 .gnus 发布最终结果解决方案的样子。

;; excerpt from .gnus
(defvar smtp-accounts
  '(
    (ssl "first@onedomain.com" "mail.onedomain.com"
     26 "first@onedomain.com" secret)
    (ssl "second@onedomain.com" "mail.onedomain2.com" ;; <-- This is the new alias in my /etc/hosts
         26 "username@onedomain.com" secret) ;; <-- Added these two lines
    ))

;; excerpt from .authinfo
machine mail.onedomain.com login username@onedomain.com port 26 password MyPASS
machine mail.onedomain2.com login username@onedomain.com port 26 password "MyOtherPASS"

;; excerpt from /etc/hosts. The IP was obtained by pinging my mail.onedomain.com
69.89.31.60 mail.onedomain2.com onedomain2

Answer 1

message-mode 的 X-Message-SMTP-Method header 字段也可能有帮助。

例子:

X-Message-SMTP-Method: smtp smtp.fsf.org 587 other-user
