Hello all,
It is possible that port 25 is closed for new accounts. This is something we have been doing to reduce spam on our network. Please do not think that we are accusing you of sending spam, it is more that we simply cannot accurately determine who is going to send it.
Stopping spam is a constant fight, so we have implemented some restrictions on newer accounts. To qualify for the ability to send out email, we do require accounts to wait 60 days before we can look into removing the restriction. Once your account has reached 60 days of stable use, please do reach back out to us so we can look into this for you.
Hope that helps! Regards, Alex
From what I understand you may need to raise a ticket with Digital ocean. Some IP’s / VPS can be blocked. ( From what I have seen )
Also, check your outgoing iptables / firewall rules to be sure you are not blocking it yourself.
I have also issue with outgoing port 25, I tried every thing as mention in digitalocean’s community but still facing issue and No one answer my ticket from Digitalocean support system, How disappointing :(
