GNU通過同一服務器向多個外發帳戶發送電子郵件而不使用imap

Question

我使用GNU和多個電子郵件地址，包括根據郵件上的FROM更改外發SMTP。 到現在為止還挺好。 但是，現在，我在同一台服務器上有多個帳戶，所以通常的.authinfo對我不起作用。 似乎答案應該類似於http://www.cataclysmicmutation.com/2010/11/multiple-gmail-accounts-in-gnus/，但我不使用gmail，我不使用imap。 我正在使用SMTP和SSL。 我該如何擴展該解決方案？ （另外：我正在使用gnus-posting-styles來幫助發送帶有適當地址的郵件，這是值得的）

以下是我的.gnus的相關部分。 請注意，我正在嘗試使用webdev @ [ME] .com，這是[ME] @ [ME] .com（兩個服務器都是相同的）的補充。 我需要在這里和我的authinfo中做些什么來完成這項工作？

解

我正在尋找的答案如下。 為了完整起見，我使用/ etc / host文件，.authinfo和.gnus發布我的最終結果解決方案。

;; 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

消息模式的X-Message-SMTP-Method標頭字段也可能有所幫助。

例：

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

Answer 2

我有一個類似的設置，我在gnus中使用發布樣式在幾個電子郵件帳戶之間進行選擇。 我曾經如上所述這樣做，為同一主機定義了不同的別名，具有authinfo條目。 它看起來像這樣：

Contents of ~/.authinfo.gpg:
machine imap.gmail-alias1.com login me@hosteddomain.org password pass port 993
machine imap.gmail-alias2.com login me@gmail.com password pass port 993
machine smtp.gmail1.com login me@hosteddomain.org port 587 password
machine smtp.gmail2.com login me@gmail.com port 587 password

Partial contents of /etc/hosts:
# So I can use multiple gmail accounts in authinfo
# should be same address as imap.gmail.com
173.194.70.108 imap.gmail-alias1.com
173.194.70.108 imap.gmail-alias2.com

74.125.136.108 smtp.gmail1.com
74.125.136.108 smtp.gmail2.com

但我切換到使用postfix發送郵件。 您可以做的是設置postfix，以便它（例如）可以接收USER1 @ gmail.com，USER2 @ gmail.com，USER3 @ googlehosteddomain.com的郵件並將所有郵件發送到smtp.gmail.com ，同時使用適當的每種情況下的帳戶憑據。 這要求您安裝Postfix程序，並設置文件* / etc / postfix / sasl_passwd *和* / etc / postfix / sender_relay *。

Answer 3

我在同一個郵件服務器上有多個SMTP帳戶，只需為每個郵件帳戶定義一個具有不同“域”的主機文件條目。

Answer 4

我認為更好的解決方案是將所有smtp auth詳細信息放在~/.authinfo.gpg並（重新）將smtpmail-smtp-user設置為要發送的用戶帳戶。 然后smtpmail.el將使用此條目的密碼，即使有多個條目具有相同的服務器。 來自smtpmail.el ：

(defcustom smtpmail-smtp-user nil
  "User name to use when looking up credentials in the authinfo file.
If non-nil, only consider credentials for the specified user."
  :version "24.1"
  :type '(choice (const nil) string)
  :group 'smtpmail)
