LISTSERV documentation says:

LISTSERV includes support  for automatic deletion of  users whose account
has  expired  or whose  system  has  permanently disconnected.  When  the
delivery error  is generated by LMail  (any version), MX V3.2  or higher,
PMDF V4.2 or higher, or LSMTP(TM) , which all implement the same delivery
error format, LISTSERV may be  able to automatically process the delivery
error  and take  action based  on the  value of  the "Auto-Delete="  list
header keyword.  The unix  versions of  LISTSERV also  support sendmail's
delivery error format.


Is the simpler format documented anywhere? DSN is too complicated for what
I want.

Thanks.
