Hello
I was settings up vaultwarden in my org, and everything was working perfectly, expect the SMTP configuration.
When trying to send mail we get the error “[vaultwarden::mail][ERROR] SMTP error: response error: incomplete response”
I suspect this is because of o365 SMTP relay gives no response even when you correctly connect.
Config:
Then i thought i could just use our on-prem SMTP relay. Which uses host based filtering, but then it dosen’t give a login method.
So VaultWarden throws the error:
2025-01-06 09:08:15 [2025-01-06 08:08:15.391][lettre::transport::smtp::client::async_connection][DEBUG] << 250-smtp.fmk.dk Hello [10.32.13.140]250-TURN250-SIZE250-ETRN250-PIPELINING250-DSN250-ENHANCEDSTATUSCODES250-8bitmime250-BINARYMIME250-CHUNKING250-VRFY250 OK

Config (couldt not uploade 2 images, so created it as a table instead):
| Setting | Value |
|---|---|
| Enabled | True |
| Use sendmail | False |
| Sendmail commaind | |
| Host | smtp.example.com |
| Secure SMTP | starttls |
| Port | 25 |
| From Address | srvcvaultwarden@example.com |
| From Name vaultwarden | Vaultwarden |
| Username | |
| Password | |
| SMTP Auth Mechanism | |
| SMTP Connection TimeOut | 30 |
| Server name sent during HELO | |
| Embed images as email attachments | True |
| Accept invalid certs | True |
| Accept Invalid Hostnames | False |
I have tried diffrent Auth methods non worked.
So i was wondering if any of you have run into one of the errors and knew how to fix it, or just knew in which direction to look.
