[Help needed] issue self hosting lemmy and email smtp

Morethanevil

I read on github that it is a bug to use external smtp servers. You need to configure the postfix Container or wait for an update to use external SMTP.

I use external smtp and have had no problems over several versions.

OP, please share your config.hjson (redacting all sensitive info)

Working perfectly fine here as well. From the backend’s perspective, a relay or an external server shouldn’t be functionally different whatsoever.

Could you help me with the setup of the SMTP via lemmy.hjson?

Mine looks like this:

email: {
    smtp_server: "smtp.domain.de:465"
    smtp_login: "admin@domain.de"
    smtp_password: "secretpass"
    smtp_from_address: "admin@domain.de"
    tls_type: "tls"
  }

That really should work, I would check for potential firewall issues or something.

Mine is basically identical to yours:

email: {
    smtp_server: "mail.h.max-p.me:465"
    smtp_login: "lemmy@max-p.me"
    smtp_password: "REDACTED"
    smtp_from_address: "lemmy@max-p.me"
    tls_type: "tls"
  }

It’s possible your server is slightly misconfigured and actually serve plain traffic on 465 and requires the use of the STARTTLS command.

Can you reach your server with openssl?

openssl s_client -connect smtp.domain.de:465

This should end up with something like that:

    Start Time: 1688422790
    Timeout   : 7200 (sec)
    Verify return code: 0 (ok)
    Extended master secret: no
    Max Early Data: 0
