My digitalocean discourse droplet can’t send mails. The error I get is:

```
Delivered mail d8f9bf03-a3ce-4b42-8226-fc4f40a9c724@foo.barbar.com (5099.4ms)

Job exception: 504 5.7.4 Unrecognized authentication type [BL0PR0102CA0036.prod.exchangelabs.com]

```

My settings are:

```
  DISCOURSE_SMTP_ADDRESS: smtp.office365.com
  DISCOURSE_SMTP_PORT: 587
  DISCOURSE_SMTP_USER_NAME: foo@bar.com
  DISCOURSE_SMTP_PASSWORD: "mypassword"
  DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)

```

I have tried telnet from the droplet and it gives no errors:  
`telnet smtp.office365.com 587`

What could be the problem? I have tried the smtp settings combination locally from python and it works so I assume that’s not the problem.
