From the LISTSERV Reference Card:
Options for mail headers of incoming postings (choose one):
FULLhdr or FULLBsmtp -> "Full" mail headers
IETFhdr -> Internet-style headers
SHORThdr or SHORTBsmtp -> Short (default) headers
DUALhdr -> Dual headers, useful with PC
or Mac mail programs
Sooo
SET listname SHORT
or something else beside DUALHDR (which is mutually exclusive).
