Sending emails from Firebase Cloud functions using Port 25


(Karthik Kamalakannan) #1

I’m relying heavily on Firebase’s infrastructure for some of my applications. I currently use Firebase Cloud Functions to send emails to via my third-party servers.

Unfortunately, looks like I’m not able to use Port 25 to send out emails from Firebase Cloud Functions to my Mail Server. Can someone help me overcome this issue?

Here’s what I’m trying to do:

  1. I use Firebase Cloud Functions to perform some calculations
  2. Once something happens, an email is triggered via third-party mail server

Thanks in advance. :slight_smile:
