Cannot Send Emails Out on Vultr
-
If you are using Vultr for hosting, you might run up against an issue that you can not natively send out emails from your systems there, even though emails can be received. This is because outbound port 25 is disabled by default on Vultr's firewall. This is to prevent spam being sent from systems that are not intended to be used as email servers.
To open port 25 for SMTP sending, you just need to open a ticket to Vultr support. Response times are around one minute, it is very, very fast. Once you open the port with them directly, you need to go into your Vultr control panel and do a full platform level restart of your VM instance for the port to be open.
That's it. Quick and easy.

Why not just change the SMTP port?

You can't. SMTP uses port 25. Changing the outbound port only works if you control every posssible email destination.

I swear I posted a thread about this when I first setup a phone system on Vultr. Maybe not. But it is that simple to get approved.

Ah duh. I was thinking you were just sending email to yourself for some reason. Never mind.
