Using sendgrid with rails so I can send emails from Google Cloud Platform on port 465. Isnt working

Question

Its my first time playing around with sending emails in an application. I'm using an instance on the google cloud platform and found out that they block sending emails form port 465. They have an work around solution which is using a third part to send the emails. I decided to go with sendgrid. But there are a few different options for setting it up and I'm not sure which is the one I'm supposed to use for CGP to allow me to send emails using SSL.

I followed this tutorial by sendgrid but I still have the instance blocking port 465. Am I supposed to do it a different way? If so what am I supposed to do?

Answer 1

To send email via SendGrid from gcp, you need to use port 2525.

See this link for more information on using SendGrid.
