[BUG] SMTP config has no var for FROM about paperless-ngx HOT 8 CLOSED

Those settings just correspond to the Django settings here: https://docs.djangoproject.com/en/4.2/topics/email/. Which I assume just uses Python's smtplib. As it appears to have connected to the host, i would suggest lookging at your email server configuration, which is what rejected the email.

I've got several server apps using this server to send these password reset emails and such and they work. I expect to see the "[email protected]" address associated with the send attempts like I do with all my other apps, instead of a "webmaster@localhost" address. I'm a bit stumped since setting the email server env vars pass right thru to paperless but it doesn't look like the USER and PASSWORD are passed through. At first I thought this was another case where an app wasn't let me set the from address, like Ghost blog does, forcing a from address by building it dynamically but fails to build the right from address in the case of Ghost being at a subdomain. But I couldn't find any evidence in the mail server log that paperless tried to authenticate as "[email protected]"...

Ah, I wonder if it is from https://docs.djangoproject.com/en/4.2/ref/settings/#default-from-email

Knowing nothing about email, would it ever be the case where the sender would not match the host user? Like a login by x, but sent by y?

Yes, I have definitely faced a situation where the app would get all the way authenticated, send the email and the email server on the send side would reject it because the "from" address didn't match the address of the sender account. That used to be a common spam technique: send emails as some other user. But this case, I can't tell if it's authenticating at all, which pushes me to think that it's not supplying the EMAIL_HOST_USER and _PASSWORD to the email server.

I was thinking it could be possible I don't have the env vars set right (wrong names or something) especially if it changed and the docs lagged. The paperless logs don't specify what user and pass (even redacted) it tried. I'm looking for the flag to increase log level.

848cef8 will let you set the default from email. It's the only place I can think of that is coming from. But if not set, the email host user will be used instead

I had tried setting that env var too. Let me try to prepend PAPERLESS to that this time and see what it does...

You can't set it currently without overriding the settings.py file.

Gotcha. Thx for looking into it! I checked the env vars in the running docker container and DEFAULT_FROM_EMAIL is not set. I do confirm all the others are set...
