Looking at mail that *is delivered* won't tell you what happened
with mail that is lost.
You need to find out which messages disappear down a black hole.
First, make sure local mail handling is sound: analyze Postfix logs
and find out if any received mail is not logged as delivered or
returned.
Second, mail may be lost up-stream. Set up a cron job that sends
one message each hour through your mail security provider, and look
at their arrival pattern: how much delay, how much never delivered.
