Redmine

Hi

I'm facing avery weird behaviour with the forum email notifications.

They perfecctly work if I set up the configuration.yml file with the office365 SMTP datas.

BUT if I change the configuration.yml file with some internal smtp the forum email notifications are not sent anymore while ALL other email notifications (issues for example) continue to work !!!

Is there any reason why the forum email notifications work with some SMTP and with others please ?

Here is the configuration :

in the configuration.yml file :

email_delivery:
      smtp_settings:
        delivery_method: :smtp
        enable_starttls_auto: false
        address: "mail.myredminedomain.com" 
        port: 25
        authentication: :login
        user_name: "info@myredminedomain.com" 
        password: "xxxxxxxx"

Environment:
Redmine version 3.4.3.stable
Ruby version 2.4.2-p198 (2017-09-14) [x86_64-linux]
Rails version 4.2.8
