neither ``--output=sender`` nor ``--output=recipients`` is
given, ``--output=sender`` is implied.
- **sender**
+ sender
Output all addresses from the *From* header.
Note: Searching for **sender** should be much faster than
cached directly in the database whereas other addresses need
to be fetched from message files.
- **recipients**
+ recipients
Output all addresses from the *To*, *Cc* and *Bcc* headers.
- **count**
+ count
Print the count of how many times was the address encountered
during search.
Note: With this option, addresses are printed only after the
whole search is finished. This may take long time.
- **address**
+ address
Output only the email addresses instead of the full mailboxes
with names and email addresses. This option has no effect on
the JSON or S-Expression output formats.
Control the deduplication of results.
- **no**
+ no
Output all occurrences of addresses in the matching
messages. This is not applicable with ``--output=count``.
- **mailbox**
+ mailbox
Deduplicate addresses based on the full, case sensitive name
and email address, or mailbox. This is effectively the same as
piping the ``--deduplicate=no`` output to **sort | uniq**, except
for the order of results. This is the default.
- **address**
+ 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
