Perhaps you are receiving the following message for the second time. The server reported that the message could not be send because one of the addresses was faulty (due to a typo). I'm not sure whether this means that the message is withheld in total.

 ear Old Man,

Please find attached the description and circuit diagram of the PA0LQ 30 Hz wide non-ringing audio filter and mains QRM noise blanker.

Contrary to what I said in my announcement on the Reflector the device does not combat noise from fluorescent tubes. My aging memory failed me there, for which I apologize.
