Can't create user when SMTP is enabled

[michelleDeko]

Hi,

I tried setting up Revolt on my server with an SMTP server (mailcow on the same server)
But I can't register an account because of the following error:

INFO  rocket::server                                                   > POST /auth/account/create application/json:
 INFO  rocket::server::_                                                > Matched: (create_account) POST /auth/account/create
 ERROR authifier::config::email_verification                            > Failed to send email to [email protected]!
lettre error: Connection error: Network is unreachable (os error 101)
 INFO  rocket::server::_                                                > Outcome: Success(500 Internal Server Error)
 WARN  rocket::server::_                                                > Remote left: client disconnect before response started.

I'm 100% sure I the smtp settings were set correctly.
This is the error I'm getting on the website:

I also saw this error in the browser console:

Is there a way to fix this?

It appears to be struggling to connect to your mail server, have you verified the connection manually?
If you specify "localhost", it won't work because that will refer to the internal Docker network.
You can use this trick for example: https://stackoverflow.com/a/62431165

I used the domain name (mail.domain.com), not something local. I also used the same options like I do in Nextcloud for example.
