Hi all,
I would like to use Mailpit on our dev environment and for this I use a docker container and I set up a nginx proxy. When I navigate to Mailpit I see a white screen. Can anyone tell me what the problem could be? Thank you!

Best regards,
Georgii

Yeah, both of those have nothing to do with Mailpit, and must be coming from your default app (that nginx is serving, LenoClient?). Your configuration isn't complete either as it does not account for the websocket connection either. I'm not on my computer right now but I'll have a look later today to see if I can dig up anything.

Okay, thank you. Locally everything works fine (there is no nginx so no proxy), so I left the docker config as it is.
Will be glad to hear from you

Does the url you are accessing have a training slash? http://domain/mailpit/

You'll need to change that for starters, adding both a trailing slash to your proxy as well as the url you are loading. I suspect it will work after that, well the basic web UI anyway, but without websocket support for "live updates". There is a bit of info in the wiki about that.

In addition to that, you'll also need to tell Mailpit that you are accessing it under a different webroot, to in your docker compose file you'll need to add/set the environment:

    environment:
      MP_WEBROOT: /mailpit/

Hi @axllent
the routing with trailing slashes works and I can see the default UI, thank you!
Unfortunately I don't see any emails. Do you have a tipp for me, how can I configure a Mailpit as a SMTP server on our environment?

SPRING_MAIL_HOST: ?
SPRING_MAIL_PORT: 1025
SPRING_MAIL_USERNAME: ...
SPRING_MAIL_PASSWORD: ...

SPRING_MAIL_PROPERTIES_MAIL_SMTP_AUTH: "true"
SPRING_MAIL_PROPERTIES_MAIL_SMTP_STARTTLS_ENABLE: "true"

@gbalatckii I don't know anything about Spring mail (?), nor have any clue with what options you started mailpit with, so I cannot tell based on the info you have provided so far. By default Mailpit will start without any authentication requirement, and no STARTTLS support (unless you have specifically enabled those). So I'd guess:

SPRING_MAIL_HOST: ?
SPRING_MAIL_PORT: 1025
SPRING_MAIL_PROPERTIES_MAIL_SMTP_AUTH: "false"
SPRING_MAIL_PROPERTIES_MAIL_SMTP_STARTTLS_ENABLE: "false"
