Hi Team, I just spun up a new ghost instance using docker compose, everything seems to be going super well However whenerver I try ans send out invitation emails I get a big red bar at the top saying

> Error sending email: Failed to send email. Reason: Authentication required, invalid details provided. Please check your email settings and resend the invitation.

I am confused as to why this is the case although I have tried to set up the SendGrid using the avaible mail options see below for my docker compose  
version: ‘3.2’

```
services:

  ghost:
    image: ghost:latest
    ports:
      - xxxx:2368
    environment:
      url: url
      mail__transport: SMTP
      mail__host: smtp.sendgrid.net
      mail __options__ port: 587
      mail __options__ auth __user: apikey
      mail __options__ auth__pass: SG.xd
      mail __options__ service: Sendgrid
    volumes:
      - /opt/ghost_content:/var/lib/ghost/content

```

Are you hosting on Digital Ocean? My mail quit working yesterday and I don’t know why. I think Digital Ocean is blocking. I use Mailgun and I get a similar error and the error comes up so fast that it leads me to think it is blocked at the server.
