Email on Idoc Failure with Status 56 64 68 69 70

We have standard inbound idoc processing for Basic Type : DELVRY01 and Message Type : DESADV using the function module IDOC_INPUT_DESADV1.

We currently have a requirement to send an email, when any of these type of Idocs fail with status 56, 64, 68, 69 and 70.

Where would be best place to provide this solution to send an email to a particular user when the Idoc fails with the above status?
