amazon SES on Google Cloud Computing instance VM using postfix

Question

can anyone help me configure postfix to use with amazon ses please.. i can successfully follow instructions here using sendgrid https://developers.google.com/compute/docs/sending-mail and it is working fine using sendgrid..

But i would like to adjust settings to use amazon SES instead of sendgrid, I am not even sure if that is possible seems google has blocked all smtp ports.

any help greatly appreciated...

I have tried these.. http://docs.aws.amazon.com/ses/latest/DeveloperGuide/postfix.html but did not work running debian 7 google VM instance

Answer 1

solved it already.. in case it helps others Google Instance VM can use port 2587. I unblocked that from my console, then used the popular phpmailer php library to send mail...
now all is working perfectly..

finding the port was hard.. google documentation does not make that clear..

Answer 2

I finally got it to work too, and as per to the comments in the answer, I will provide how I did it step by step.

Amazon uses the mentioned port in the answer, and this is mentioned here, under STARTTLS: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-connect.html#smtp-connect-secure-tunnel

I have an already working postfix installation and followed the guide posted in the question: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/postfix.html

I installed stunnel on my ubuntu using:

sudo apt-get install stunnel4

Followed the guide here: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-email-smtp-secure-tunnel.html

And the content of the final stunnel config file:

[smtp-tls-wrapper]
accept = 2525
client = yes
connect = email-smtp.eu-west-1.amazonaws.com:2587
delay = yes
cert = /etc/stunnel/mail.pem
protocol = smtp

Important Notes:

• The "protocol" config value is not mentioned in the docs, but it won't work without it
• Replace the "connect" value to match your region, but keep the port as 2587.
• As mentioned in the answer, you need to allow port 2587 from your google cloud console
• There is also port "2465" available for "TLS Wrapper" wich should also be possible to use with Google's Compute Engine.
