Original GitHub issue: https://github.com/dani-garcia/vaultwarden/issues/4283

I have working exim4 on server. Vaultwarden installed without Docker.

  • vars USE_SENDMAIL=true and SMTP_FROM=user@mysite.com defined in /etc/vaultwarden.env;
  • user vaultwarden added to group Debian-exim
  • changed rights to directory /var/spool/exim4 from 750 to 770 (owner Debian-exim and group Debian-exim).

But i have error during in "Test SMTP" section:

Error sending SMTP test email
Sendmail client error: internal client error: 2024-01-29 12:32:11 1rUNzv-001b0k-31 Failed to create spool file /var/spool/exim4//input//1rUNzv-001b0k-31-D: Read-only file system

Then i add folowing lines to vaultwarden systemd service like this:

RestrictAddressFamilies=AF_UNIX AF_INET AF_INET6 AF_LOCAL AF_NETLINK
ReadWritePaths=/var/lib/vaultwarden /var/spool/exim4

But have error:

Why does he send emails on his own behalf and not on behalf of exim?

Emails is sent without problems via sendmail (sendmail is symlink to exim4):

echo "Subject: sendmail test" | sendmail -v user@mysite.com`

Environment:

  • Debian 12
  • Exim 4.96
  • Vaultwarden:
    • Server Installed - 1.30.1-edf7484a
    • Server Latest - 1.30.1-4b9384cb
    • Web Installed - 2024.1.2
    • Web Latest - 2024.1.2
    • Database - SQLite: 3.44.0

Well, the vaultwarden user is the one executing the exim or sendmail command.
So, not really strange i think.

I do not have the exact workings, but it just executes the command provided in the config.
Best way to simulate this is by running it like this via the shell.

echo "Subject: sendmail test" | sudo -u vaultwarden sendmail -v user@mysite.com

I did some quick tests locally. And it seems to work fine for me, and I'm running Vaultwarden via a normal user.

This doesn't really seem like a bug/issue on the Vaultwarden side, but more a configuring issue with exim4 (Which is a hell in my opinion).

Maybe other users here know something, and therefor I'm moving this to Discussions.
