Due to an upgrade project we would like to prevent K2 from sending mails to the users. We have setup a local smtp server on the windows server 2012 hosting K2.
When running through the Setup manager we are getting an error (Connection attempt to the smtp server failed) during SMTP Settings.
The local smtp server is working correctly. We have test it by sending mail from powershell.
Has anyone succeeded K2 Setup with a local smtp server?
Or how do you handle outgoing mails during an upgrade?
