Nathan: In the tread about filters, you made reference to the latest build date for Listserv 1.8d (which I am running under Digital Unix 4.0b), which you said was in September. The build date for my Listserv is from August 19, more than a month older. Is there much of a difference in Listserv between those two build dates? Obviously, there's the change in the way multiple mail headers are handled, but what else, if anything, was changed in this latest build date?
