SES端口在GCP中被阻止

Question

I have an application that is hosted on a GCP machine. This application is supposed to send a mail via AWS SES service.

From what I've seen in GCP documentation, all default SMTP ports are blocked in GCP machines.

is it possible to unblock one of the ports or use another port for sending the mail?

Thank you, Maya

Answer 1

Use 2587 port instead of 587. http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-connect.html#smtp-connect-starttls

Look amazon SES on Google Cloud Computing instance VM using postfix

Answer 2

2525端口不受阻碍，所有主要供应商都为2525 smtp端口提供支持。
