The settings you're using looks a little confusing, some places you indicate that you want to use SSL/TLS and other places you don't.
Here is the settings you should probably be using(partly based on the link i posted):
Standard SMTP(not using a secure connection)
SMTP server address and protocol: smtp-relay.gmail.com
SMTP server port: 25
SMTP username/password: [If required]
Verify SSL certificate: No
Verify SMTP peer name: No
Allow self-signed certificate: No
Secure SMTP with SSL/TLS:
SMTP server address and protocol(You may have to prepend the ssl:// or tls:// protocol to the address): smtp-relay.gmail.com
SMTP server port: 587 or 465
SMTP username/password: [If required]
Verify SSL certificate: [your choice]
Verify SMTP peer name: [your choice]
Allow self-signed certificate: Yes if certificate is self-signed otherwise No(No is probably the right choice in your case)
The settings you want for you forum?
I cannot see where the setting of this is, Can you describe this a bit more? I need screenshots possibly.The alternative described in the link J. H. Rasmussen posted is to use the Google Workspace SMTP relay service, as described in the "Use SMTP relay service (recommended)" section. You must enable this in your Google Workspace administration console, and assign the IP address of your web server as being the IP address authorized to send mail on your behalf.
Once you have the Google Workspace SMTP relay service setup to allow your phpBB web server's IP address, the recommended phpBB settings:
- Use SMTP server for email: Yes
SMTP server address and protocol: smtp-relay.gmail.com (do not add any ssl:// or tls:// prefix)
SMTP server port: 587
Authentication method for SMTP: NONE
SMTP username: blank/empty
SMTP password: blank/empty
Verify SSL certificate: No
Verify SMTP peer name: No
Allow self-signed certificate: No
