Issue was mail struck in Barracuda due to sending emails to more than allowed list in Barracuda
Wait for it to time-out, or delete it WITH NDR. Read the NDR for explanation.

If Wireshark is already installed, start listening on port 25, force queue, read traffic to check the problem (hopefully you don't use TLS)
