No verification emails (selfhosted)

[dfertw8474]

I've installed the latest Rallly version via Container Manager on my Synology NAS.
So far, I was able to create the user, create a poll.

However, it's not possible anymore (got twice a code) the get the verification (6digit) codes.
Using the same SMTP account as for my NAS (for notifications) with my own domain. Not Google or something else.
All other external mails or the host notification mails to the target email account for the user (same domain) are coming in but no one from Rallly.
Nothing in SPAM or so.
I have a lot of mailboxes with the provider and my domain, and all the other stuff is working.

How can I find out what's going on here? Are there any send mail logs somewhere?
It must be an issue here with the mail sending stuff in Rally, nothing to do with my mail accounts.

Environment stuff in the compose.yaml:

environment:
DATABASE_URL: postgres://ralllyuser:redacted@rallly-db:5432/rallly
SECRET_PASSWORD: redacted
NEXT_PUBLIC_BASE_URL: https://redacted.example.com
SUPPORT_EMAIL: redacted@mydomain.de
SMTP_HOST: smtp.strato.de
SMTP_PORT: 465
SMTP_SECURE: true
SMTP_USER: redacted@mydomain.de
SMTP_PWD: redacted
#EMAIL_LOGIN_ENABLED: true #or false to Limit Login to SSO. Remove the # in front of EMAIL_LOGIN_ENABLED
REGISTRATION_ENABLED: false #or false to Disable User Registration.

If you're not seeing any error logs in the rallly container then I'd assume the email is being sent successfully and the answer will be somewhere in the logs of either your SMTP server or the receiving mailbox.

That's what I'm getting in the Container Manager for the Rallly container:

⚠️ Certificate validation is now enabled by default for SMTP connections. Set SMTP_REJECT_UNAUTHORIZED=true to silence this warning, or SMTP_REJECT_UNAUTHORIZED=false if using self-signed certificates.

As the log suggests, you can try setting SMTP_REJECT_UNAUTHORIZED=false to allow sending emails with certificates that aren't signed by a trusted CA, such as self-signed certificates.

Added the option, but no avail.
Mails from Rallly are not coming in.
Changed to SMTP port 587, but same thing.

Unfortunately, I can't check for SMTP logs on the provider's side, I have there only webspace/database logs which I can check.

[dfertw8474]

OK.
I deleted completely the project, pulled the whole stuff again and re-created the account.
Got the verification email.

The question is, what happens if I log out and try to log back in. If I will get the verification emails again.
We'll see.

I rather prefer to log in via the password and not via a magic link/verification email

A short update: seems to be working now, signing in with the password.

One thing: when a participant is using his email address in the poll, the email answer is in English, even if the interface is set to German.
Is there a way to configure the email answers to be in the same language?

Are you running the latest version? You can check the version by going to /api/status.

Edit: Nevermind. I had a look and can see that there is a an issue here preventing the user's preferred locale from being passed along. Will work on a fix. Thank you for reporting.

Thanks for looking into it!

Got it!
{"status":"ok","timestamp":"2026-04-21T16:15:41.459Z","version":"v4.9.0","environment":"production","database":"connected"}

But it's still in English, not in the language the GUI is.
