You will need to gather some information before you start installation:

      • What is the DNS hostname for the machine on which LISTSERV is going to be installed?  This is something like LISTSERV.YOURDOMAIN.COM .  It must be a fully-qualified domain name (FQDN) and it must map to an A or MX record as noted above in the networking requirements.  While it is possible to use a bracketed IP (eg, [10.0.0.24]) for testing purposes, the use of bracketed IPs in production is not supported and not recommended.
      • What SMTP server do you intend to use for LISTSERV's outgoing mail?  Like the hostname for the LISTSERV machine, this must be an FQDN hostname listed in DNS.  If you will be installing a compatible third-party MTA on the same machine as LISTSERV then the answer to this question is identical to the answer for #1.  Otherwise this must be the name of an external machine, i.e., one running sendmail or some other SMTP implementation that can accept LISTSERV's outgoing mail for delivery.  (If you will be installing a third-party MTA on the local machine, you will probably still want to identify an external SMTP machine to use temporarily to test LISTSERV prior to installing the local MTA, which is the recommended procedure.)
      • What are the email addresses for the LISTSERV maintainers (the person or persons who are authorized to create lists and operate/maintain the server)?
      • What drive and directory are you going to install LISTSERV into?  (The installation script defaults to C:\LISTSERV; if you have more space on another drive, e.g., a RAID array or other large disk, you will want to install LISTSERV on that drive rather than on C:.)
      • What program group or folder do you want LISTSERV's icons to be placed in?
