Integrate Pepipost With Xenforo

XenForo by default will be able to send email on most servers using PHP's default mailing settings. However, if you wish to control more aspects of the mail sent by XenForo, you can switch over to third party SMTP service provider like Pepipost.

To configure SMTP on Xenforo, simply log into your admin control panel, go to Options and into the Email Options group. We have provided a step-by-step guide to configure Xenforo via Pepipost

Step 3:

Now, you are on the Email Options page. Now, it’s time to setup your sending email address. This is the email address which will appear as SENDER when someone receives your forum email. Please follow the below instructions to setup the Sending domain parameters:

Default Email Address: This is the default email address that emails will be sent from. It should not be ISP’s domain like or This should be some email address which belongs to your own domain e.g.

Note: The sender domain should be configured and verified on Pepipost. You will be unable to send emails unless the sending domain is verified and approved on your Pepipost admin panel.

Contact Email Address: Email address where board-related messages will be sent. Keep this uncheck as it is not supported by many SMTP providers.
Default Email Sender Name: If specified, emails sent by XenForo will default to being from this name. If no value is entered, the board name will be used. Ideally it is a good practice to have board name in the default sender name.
Email Transport Method: Select the “SMTP” radio button here and enter following details:

1. Host:

2. Port: Port can be 25, 587 or 2525. Most of the shared hosting providers block these port to protect their network from spamming. Hence, if even after doing all the setup, your emails are not getting delivered, then try contacting your hosting provider to unblock these port for outgoing SMTP connection.

3. Authentication: Select the radio button as “User Name and Password” and enter your Pepipost’s username and password.

Encryption: You can choose anything based on your requirement. But, to avoid any integration related challenges it is suggested to keep it None. xenforo integration
