   Good question, sorry if I elaborate a bit.   
      
   I don't use Postfix or traditional MTAs. My stack is:   
      
   -- Web Interface → YAMN client → Pluto2 → Tor → YAMN mixnet   
      
   YAMN Configuration

   Pluto2 SMTP Relay   
   Pluto2 (https://github.com/gabrix73/pluto2) is for anonymous relay.   
   It logs operational events (connections, batches, relay status) but not:   
      
   Message content or headers   
   Email addresses   
   Message IDs beyond 24h in-memory replay cache   
   Timing correlation data   
      
   Data Persistence   
      
   Pluto2 message ID cache: RAM only, 24h expiry   
   YAMN pool: temporary files, shreded after send   
   No database, no persistent queues   
      
   Design Philosophy: Only log what's needed for system reliability, never   
   message metadata.   
      
   Any advice for improvments is welcome.
