Forum email notifications only work with some SMTP ??
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 :
Redmine version 3.4.3.stable
Ruby version 2.4.2-p198 (2017-09-14) [x86_64-linux]
Rails version 4.2.8
Database adapter Mysql2
