If you don't see Mindspring etc. activity in your logs, then
- Their servers are not connecting to your machine, for reasons
that have yet to be determined (no glue records for kasdivi.com
at the top-level DNS servers, sender does not like your generic
reverse DNS record, ...).
- Their servers do connect, but their activity is lost in all your
verbose logging.
I would start with turning off Postfix verbose logging, then monitor
the logfile for sessions that fail repeatedly with "lost connection",
"timeout" and other abnormalities.
