Unless the MUA is able to switch automaticaly between different submission services
depending on the From field, this does not seem very practical ?

You could perhaps use msmtp as a sendmail "replacement" for that MUA and
then configure it to change the submission service based on the From.

Thanks,

Don't most MUAs do this? mutt does, as well as Apple Mail (where each
from is tied to a specific account, which holds the right "submit"
service).

Maybe how to do this should be added to the wiki, then.
It only provides instructions for MTA (exim and postfix).

There are a LOT of MUAs... So if you give text to DSA, im pretty sure 
they are happy to include it (thats how  Colins exim and my postfix 
stuff got there).

For Fairmail (pretty good Android MUA) its inside its Settings, Base 
ones, Identities. Within an identity you can configure individual SMTP 
servers for sending (and much more). Then when you send you can select 
your from and it uses the settings for whichever sender you selected.
In Thunderbird (Desktop) you can configure entire accounts (though 
.debian.org doesnt offer IMAP) and within an account there is a "Manage 
identities" button. Behind it you can add multiple identities and for 
each one you can select the outgoing SMTP server when you send mail 
using this identity.

(Now someone please make this text nicer so it can go on the DSA page)

This is what I have for Mutt (note that I use pass to store the
mail-submit password):

```
set my_debian      = 'alexm@debian.org'
set my_debian_smtp = 'smtp://alexm@mail-submit.debian.org:587'

source "pass my-debian-mail-password |"

set my_debian_reply_hook = "my_hdr from: $my_debian"

reply-hook .                    "unmy_hdr from:"
reply-hook ~L$my_debian         $my_debian_reply_hook
reply-hook ~L.*@.*\.debian\.org $my_debian_reply_hook
reply-hook ~L.*@.*\.debian\.net $my_debian_reply_hook

set my_debian_send_hook = "\
    set signature   = '~/.mutt/signature.debian' \
        smtp_url    = $my_debian_smtp \
        smtp_pass   = $my_debian_pass \
        sendmail    = ''"

send2-hook .                    "set signature='' sendmail=''"
send2-hook ~L$my_debian         $my_debian_send_hook
send2-hook ~L.*@debian\.org     $my_debian_send_hook
send2-hook ~L.*@.*\.debian\.org $my_debian_send_hook
send2-hook ~L.*@.*\.debian\.net $my_debian_send_hook
```

I'll try to send a patch to DSA for the dsa-wiki later today.

Cheers,
Alex

I wonder — I am running a Postfix for my @gwolf.org domain. And I have
configured in its /etc/postfix/sender_relay the following content:

     @debian.org [mail-submit.debian.org]:587
     @debconf.org [mail-submit.debian.org]:587

I understand that should do the trick, right?

It's part of the solution, but if you have that, you probably also have
the rest. See "Postfix as a client config" at
https://dsa.debian.org/user/mail-submit/

Thanks :-) I guess that's where I got it from some indeterminate time ago
😉 I didn't really remember what had I done to get it working.

I believe this is fairly common functionality in mail clients, isn't it? I
thought this was part of the standard toolkit for supporting multiple
email accounts in the same client. (Gnus has supported this for forever,
but I realize most people don't use Gnus.)

In any case, one option on Debian is to run a local MTA and point your
mail client at that, and then configure that MTA to route your mail
however you want. There are instructions on how to do that at:
