My account in DO is recent and according to the support, for 60 days I have my SMTP outputs blocked. This is ridiculous.

Anyway. I installed Redmine in my droplet, everything working, however, the notification part is not, due to this lock. Even if I enter ZOHO or GMail output settings I'm not successful, it returns me "timed out".

Can anybody help me?

Redmine v3.2
Ubuntu 16.04
Rails 5.1.4
Ruby 2.3
