changing smtp server and signature depending on from address

changing smtp server and signature depending on from address

Hello,

I use several email addresses, and I would like to customize the smtp
server and the signature I use for each of them. Is there a notmuch way
of doing this? I’ve looked at
https://www.emacswiki.org/emacs/SendingMail#SmtpMail and I see that I
can set a particular header to set the smtp server, but I don’t know if
there is a feature like gnus posting styles in notmuch.

Best,

Alan

I use gnus-alias for something like that:
--8<---------------cut here---------------start------------->8---
(use-package gnus-alias
  :ensure t
  :after notmuch
  :commands (gnus-alias-determine-identity)
  :hook ((message-setup . gnus-alias-determine-identity))
  :bind (:map notmuch-message-mode-map
              ("C-c i" . gnus-alias-select-identity))
  :config
  (setq
   gnus-alias-default-identity "default"
   gnus-alias-overlay-identities t
   gnus-alias-override-user-mail-address t
   gnus-alias-identity-alist
   '(("default"
      nil ;; Does not refer to any other identity
      "Dan Čermák <*snip*>" ;; From Header
      nil ;; Organization header
      (("Fcc" . "*snip*/sent-mail")) ;; List of extra headers
      nil ;; No extra body text
      nil ;; Signature
      )
     ("posteo"
      nil
      "Dan Čermák <dan.cermak@posteo.net>"
      nil
      (("Fcc" . "posteo/Sent"))
      nil
      nil
      ))

   gnus-alias-identity-rules
   '(("personal-redacted" ("any" "snip*" both) "default")
     ("personal-posteo" ("any" "dan.cermak@posteo.net" both) "posteo"))))
--8<---------------cut here---------------end--------------->8---


Hope this helps,

Dan\r

Thank you for suggesting gnus-alias, it looks like a great fit.

I don't think notmuch has a built-in/default way of doing it, but
notmuch itself recommends using gnus-alias [1], like others have
recommended.

I myself have come up with my own system, which gets the information for
the addresses from auth-source [2]. It basically consists on an alist
that assigns an "alias" for each address and holds its information as a
plist. So, assuming I have a personal and work accounts, the alist would
be something like

  ((personal
    (:address . "jpedrodeamorim@gmail.com")
    (:name . "João Pedro")
    (:host . "smtp.gmail.com")
    (:key . "p")
    (:signature . "João Pedro de Amorim Paula
IT undergraduate at Universidade Federal do Rio Grande do Norte (UFRN)"))
   (work
    (:address . "jpedrodeamorim@work.com")
    (:name . "João Pedro")
    (:host . "smtp.gmail.com")
    (:key . "w")
    (:signature . "João Pedro de Amorim Paula
Clojure(Script) engineer at Flexiana")))

The :key is something I assign by hand to each of my mail addresses, and
which I use to quickly choose with a single character using read-answer
[3].

I also have a couple of helper functions to correctly infer the account
I am using, and the information that smtpmail [4] needs to send my
e-mails (they are also store in auth-source, no sensitive information is
stored in plain text).

If you're interested, I could follow up on this thread detailing a
little more of how I glue it all together (by "it" I mean notmuch and
Emacs built-in Message and mail libraries), with the functions I use and
all. It currently isn't available in a public repo because I still have
some sensitive information that I need to have cryptographed before
doing so.

This looks very nice, thank you for sharing. I’ll experiment with it.
