XF 2.2 No mail verification delivered (upon new registration)

[Andreas.Tech]

Hello,

I just installed xenforo on google cloud.


Now I have a problem:
New users can not register, as no verification mail arrives in the inbox.


I tested it with gmail / protonmail accounts.

Are there any SMTP / POP3 things I have to setup in the xenforo dashboard?!


What I read in the xenforo manual is, that you actually don't have to do anything here regarding e-mail sending etc.



Thanks for your help.

Does Google Cloud have php email available?

If so, you would need to troubleshoot at the server level.

If not, you would need to set up SMTP.

This is what it says:

Sending and Receiving Mail with the Mail API | App Engine standard environment for PHP 5 | Google Cloud

PHP's built-in mail() function can send emails via App Engine Mail API. This should work well with most existing code as long as it conforms to the restrictions listed in the Sending mail.

So unless there are errors in the XF ACP preventing emails from being sent, the emails have been handed off to the server.

Troubleshooting needs to take place from the server to the end user as XF is no longer involved.

Do I need to open a specific port?!

Don't want to disclose the port I opened, but I think the standard one for mail delivery right?!

(in google cloud I have to set up a firewall rule for it)

Ultimately the PHP email sending hands off to an MTA (usually on the VPS instance) that will need the port open... and frequently your delivery rates are going to be pitiful.
This is more a server related question than a XenForo.

I personally use Amazon SES for my sites transactional email. Once you get it set up it works well. There are several other paid services that you can use also.
