You need to speak to emailsrvr.com and get them to allow traffic from your vulr IP address. They are blocking you at a network level (or, possibly, Vultr are being good net-citizens and are not letting your machine send traffic over port 25?)
The issue is that Vultr is blocking 25. They want me to submit a book report everytime I deploy a new server to open 25. Does Digial Ocean or Linode block 25? If is use them, is there an easy way to install FREEPBX on their VPS’s? I know they don’t have an easy gui for ISO upload. That is why I went with Vultr. They allow custom ISO image uploads
PitzKey- What do you mean I should be able to allow this in the Vultr Router config? I am using Vultr as the hosting provider, not router provider?
It is NOT disallowed by default because there is no default firewall, you would HAVE to add a policy with cognizance, I have literally many dozens of Vultr instances, none exhibit that behavior
I have no idea what you just said . . . Was that meant for another post?
.
Vultr did confirm - they block 25 and will not open it until I submit a volume of info every time I deploy a new server
SMTP ports are blocked by default on all new Vultr Accounts and clients are asked to request removing the block off their accounts as needed.
