+ ``--deduplicate=(no|mailbox|address)``
+
+ Control the deduplication of results.

+ **no**
+ Output all occurrences of addresses in the matching
+ messages. This is not applicable with --output=count.
+

+ uniq**, except for the order of results. This is the
+ default.
+
+ **address**
+ Deduplicate addresses based on the case insensitive
+ address part of the mailbox. Of all the variants (with
+ different name or case), print the one occurring most
+ frequently among the matching messages. If --output=count
+ is specified, include all variants in the count.

+ However, if either --output=count or --deduplicate=address is
+ specified, this option is ignored and the order of the results
+ is unspecified.
