Is there a way to configure redmine to use external SMTP server, different from my Cloudron domain?

I have tried doing it editing additionl_envrionment.rb file, added there lines like
config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {
  address:              'smtp.service.com',
  port:                 587,
  domain:               'mydomain.com.au',
  authentication:       :login,
  user_name:            'me@domain.com.au',
  password:             File.read('/app/data/mypassword').strip,
  enable_starttls_auto: true
}

But it didn't work, redmine ignored that settings and tried to send email via cloudron anyway.

I am kind of struggle to understand is it the problem of OVH or the way Cloudron uses this Spamhous open relays?

Hi

I have issues with email delivery. I only use outgoing emails.

It stopped to work few days ago with errors like (real emails obfuscated):

{
"ts": 1703054108321,
"type": "deferred",
"direction": "outbound",
"uuid": "92161D3E-B024-...-B4AB-87FC379D7F7C.1.1",
"messageId": "5c5a3b3c-db5c-3029...@email.com",
"mailFrom": "app@email.com",
"spamStatus": null,
"mailbox": null,
"quotaPercent": null,
"rcptTo": [
"my@email.com"
],
"message": "Tried all MXs",
"delay": 1024
}

When I check email status in Cloudron admin I see that according to it, server IP (we hosted on OVH) is in Spamhous black list.

I went to Spamhous website, appears that it isn't black list for spam, but kind of overuse of open resolver, here is the full article

I suspect that other users hosted on OVH may be affected.

What is the best way to deal with it?

Having email not functioning isn't good, no password recovery, invites etc.
