Vultr blocks smtp out by default, see:

As a vultr user, I can say through experience all one needs to do for a port-unblock would be to send in a ticket requesting it. Their response times are apt. Got mine unblocked within the day.

I am glad they block it on default. That prevents IP block poisoning and it decreases the chance of neighboring VMs taking critical performance hits from someone mass-mailing spam.

Do you allow outbound SMTP?
Outbound SMTP is blocked by default. To lift this restriction, you must contact our support team and fill out an authorization form.

I wouldn't call that a deal breaker problem. Or that it's not working. Although, if they make that authorization too difficult, it could be. Doesn't seem that's the case though.
