Duplicate Piped DirectAdmin Replies

Problem

This information only applies to self-hosted WHMCS installations. WHMCS Cloud does not currently support email piping. Instead, WHMCS Cloud users should use email importing.

DirectAdmin is sending duplicates of piped email ticket replies.

If you see duplicate emailed replies while using email importing, see Duplicate Imported Replies.

Cause

A line in the exim.conf file is causing email piping on a DirectAdmin server to send email twice.

Solution

Add a comment character to the unseen line in the exim.conf file on the DirectAdmin server. To do this, add a # character to the beginning of the unseen line.

For more information, see DirectAdmin’s Forums.
