I was more referring to what Jared said:Concerning the API error 400 for mail piping, many apologies. There was
bug that was very quickly fixed in the 1.8.1.2 release; however, there
were a few downloads before we were able to detect and correct the
issue. Please just download and unpack the zip file from the
osticket.com download page again. There will be no database migration
necessary.
Sorry again for the confusion and inconvenience.A message that you sent could not be delivered to one or more of itsrecipients. This is a permanent error. The following address(es) failed: pipe to |/***/****/public_html/support/api/pipe.php generated by support@*****.comThis looks more like something that your email server would generate saying that it failed to deliver the message, not an osticket error.Are you seeing any errors in your php error logs?Are you seeing anything in your email server logs?
