Postfix by default deduplicates if one message has multiple identical
recipients. However Postfix cannot deduplicate different queue files
that have the same content.
So if Postfix receives three messages, and you add an always_bcc
record to all of them, then the always_bcc address will receive
three copies.
Look at the Received: headers in the duplicates and see if they
followed different paths. The maillog file may also provide relevant
details.
