Hi @groovywebfirm

Maybe your SMTP has been blocked for some reason. Did you add new firewall rules or started to use the Cloud Firewall available in the control panel?

If you didn't do anything with your firewall, then contact Support.
Create a ticket with Support in the control panel to get un-blocked.

    Thanks for your reply,

    I already sent an email to support, but it's really slow response from Support team. It looks like they have blocked it intentionally.

    We are using our droplet for staging purpose, so we send only transactional emails. I am little surprised by their gift of blocking SMTP. They could even ask me before blocking SMTP.

    Hope things get resolved soon and I don't start hating DigitalOcean!
