I’m writing this blog as I have spent 2 hours trying to setup simple SMTP via sendgrid for a phpBB forum. The documentation was pretty hopeless, so hopefully the below will make someone else’s life easier. The issue was that it wasn’t obvious what to put into the SMTP Username & SMTP Password.
The correct config is:
Use SMTP server for email: = Yes
SMTP server address: = smtp.sendgrid.net
SMTP server port: = 587
Authentication method for SMTP: = PLAIN
SMTP username: = apikey (just that… i.e. apikey, not YOUR apikey, just the letters “apikey”)
SMTP password: = Your actual API Key from sendgrid
Verify SSL certificate: = Yes
Verify SMTP peer name: = Yes
Allow self-signed SSL certificates: = No
