Ports aren’t blocked unless you block them yourself with a firewall. If you’re using zoho as your mail provider I suggest you contact them since they’re most likely the cause of the issue.

Thank Aprexer!
I checked this for 3 days.

  • Firewall donot do this. I know use Firewall
  • I checked by scan port 465, 587, .., at https://mxtoolbox.com and see those port blocked Please help me!

Hello iamzum,

I also have problem like you but my droplet open port 465 & 587 and I use SMTP Plugin with SMTP Zoho but it can’t send anyone.

Please help

My IP 139.59.102.50

Hi iamzum,

I am facing the same problem as port 587 is blocked by DO so my web app cannot send outgoing emails. I opened a ticket [Ticket #578581]. But DO support has not replied for a couple days. Ticket is still open unsolved.

Same problem here and same support by DO, I still waiting for a response since 4 days ago… terrible support.

At least could you give me an IP to scan with?

Hello, Aprexer.
can you help me? Please!

  • Port 465 is blocked inbound but it can send outbound, its a problem with zoho not digitalocean. Also its using zoho to send emails so its nothing to do with your server.

I’m suddenly facing this issue too. It’s working fine before it. Waiting for DO support’s response too

I am also experiencing this issue.
