Sometimes tickets are created by another system sending an email to our support system, using one of our support addresses.

We would usually then receive one auto-response into the same ticket, advising the ticket had been created.

We are now receiving multiple copies of the same auto-response. The only way to fix it is to split out one of auto-responses into another ticket and close it.

I would like to know if we can stop the auto-responses to our own support address, or how to fix the new issue.
