About three weeks ago, I started seeing the following in logwatch/postfix section:

 Unrecognized warning:
     stdin: unexpected EOF in data, record type 78 length 128 : 1 Time(s)
  
 **Unmatched Entries**
 
 fatal: No recipient addresses found in message header
 fatal: uid=0: malformed input

I can see no cases where delivery is failing, but the errors persist. This machine is only responsible for collecting about 5 messages a day from some local servers and sending them out to an outside smtp server.
