[BUG] - SMTP fails with timeout

[dvnkln]

First Check

• This is not a feature request.
• I added a very descriptive title to this issue (title field is above this).
• I used the GitHub search to find a similar issue and didn't find it.
• I searched the Mealie documentation, with the integrated search.
• I already read the docs and didn't find an answer.
• This issue can be replicated on the demo site (https://demo.mealie.io/).

What is the issue you are experiencing?

Fresh install. Trying to setup email and test it fails with a timeout. It works with the exact same settings in multiple other applications.

I made sure:

• the smtp is reachable on the docker host
• the smtp dns is resolvable on the Mealie container
• the credentials work (currently using them in other applications)
• the credentials are passed correctly to Mealie

My SMTP provider is Strato.
I'm currently using secrets to pass the credentials and made sure the container is able to read them.
Nevertheless i tried passing them as plaintext directly in the compose file which didn't help sadly.

Steps to Reproduce

1. Deploy your container
2. Make sure you set the SMTP EV
3. Go to Site Settings -> Test Email

Here's my compose:

    secrets:
      - smtp_mydomain_user

Mealie seems to be reading the settings correctly.
