Jane: It sounds like the ISP's methods are B.A.D. -- broken as designed. There are a couple of LISTSERV subscriber options that affect the appearance of the RFC822 headers (and L-Soft has already mentioned some list defintion keywords). SET listname FULLHDR or IETFHDR or SHORTHDR or DUALHDR or SUBJECTHDR These won't affect MAIL FROM. <rhetorical> LISTSERV(R) has been working very nicely [stood the test of time] for 2 decades. I wonder how long this ISP will be in business? I would be glad to approve a C/R if they paid me $100 (or Euros) for each. /P -- -- Pete Weiss
