How to Set Up Email Piping for Support Tickets
WHMCS · Self-help guide
Email piping lets customer emails become WHMCS tickets or ticket replies. First, create the support department in WHMCS and note the department email address. In WHMCS, copy the piping command or pipe script path shown for your installation. Then log in to the mail control panel for that support mailbox and create a forwarder or pipe to the WHMCS script, depending on your hosting environment. Send a test email from an external address and confirm it appears as a ticket in WHMCS. Reply from WHMCS and confirm the customer receives the response. If piping fails, check the mailbox address, file path, permissions, PHP path, spam filtering, and whether your server allows email piping.
