Cann't send to gmail

Open nhcka opened this issue 5 years ago • 3 comments

I setup mail server on google cloud using VM Instance. I can receive mail from gmail, but can not send to it.

Error:

Diagnostic-Code: X-Postfix; connect to alt4.gmail-smtp-in.l.google.com[173.194.209.26]:25: Operation timed out

Because Google blocks outgoing port 25. How do I change to port 587 to send mail?

Hi, most services won't accept incoming mails on port 587. Please have a look on https://cloud.google.com/compute/docs/tutorials/sending-mail
