We are running Listserv 1.8d (the latest version) under Tru64 Unix 4.0D with the latest qmail in place of sendmail. We are having a heck of a time getting Listserv's outbound e-mail to be identified as coming from the host "listserv.temple.edu". You see, "listserv.temple.edu" is a CNAME for "cronkite.ocis.temple.edu" and on many of the systems I use, Listserv's e-mail comes identified correctly, including a host I use outside of Temple's domain, but for some hosts, the mail from our Listserv comes identified with the host as "cronkite.ocis.temple.edu" which we do not want. We tried tweaking qmail any number of different ways so we can only conclude that Listserv is injecting its mail with "cronkite.ocis.temple.edu" as the host name. Any information that would lead us to a solution that works across all Internet hosts would be appreciated, espcially HOW Listserv directs outbound e-mail. Also, how does Listserv deal with environment varialbles passed to Listserv? Thanks
