Hi, i just checked that i’m not in any blacklist and also i my firewall is opened. My java application connects to Gmail SMTP to send e-mails, but once i moved my app to Digital Ocean, the same code i always used cannot connect to SMTP Gmail saying connect timeout.
Any clue on what’s is happening?
I thought i was missing the Reverse DNS of my droplet but i already corrected that without success.
Thanks for helping.

Hello! I have similar problem… GMAIl is not working in DO servers. But work in (same code) in the servers of other company. I suppose it is problem of DO server settings. Please can you help me. Gmail settings:
Host name: smtp.gmail.com
Port: 587
Timeout: 1000
User name: noreply.bridgepharm@gmail.com
Password: ••••••••••••••••
Protocol: SMTP Aut…: true Start TLS: true
Hello marciomalewschi
To curb a recent increase in abuse and SPAM, DO has an initial SMTP block on new accounts created in certain contexts. If you file a support ticket (https://cloud.digitalocean.com/support) the team should be able to lift that for you after some manual account verification.
