Just to point out this actually is valid. Text in parentheses is a
comment. See RFC 5322 section 3.2.2. Also this quote from section 3.4
which describes the format used above:
Note: Some legacy implementations used the simple form where the
addr-spec appears without the angle brackets, but included the
name of the recipient in parentheses as a comment following the
addr-spec. Since the meaning of the information in a comment is
unspecified, implementations SHOULD use the full name-addr form of
the mailbox, instead of the legacy form, to specify the display
name associated with a mailbox. Also, because some legacy
implementations interpret the comment, comments generally SHOULD
NOT be used in address fields to avoid confusing such
implementations.
Best,
Tim
