Redmine

Hi everyone,
I am trying to configure Redmine to send email notifications.
I know that Google in May 2022 blocked the "Access less secure apps" option so I assume it is no longer possible to use GSuite for sending emails with Redmine (I also tested following the guide to send emails from my Gmail account but nothing works...).
I would like to configure Redmine to send emails from an email address with domain-name.com domain registered on Office 365 but bought on Siteground. I have already tried looking online at solutions but none worked, this is my current configuration.yml file configuration:

production:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      enable_starttls_auto: true
      address: "smtp.office365.com" 
      port: 587
      domain: "domain-name.com" 
      authentication: :login
      user_name: "my-email@domain-name.com" 
      password: "my-pass" 

This is the error I get back on Redmine's page:

An error occurred while sending an email (501 5.1.5 Recipient address reserved by RFC 2606 )

Can anyone help me solve this problem?
