Many Mail Domains, One Machine: The Forwarding Mailer

Hal Pomeranz
NetMarket/CUC International


With the explosion of domain registration in the last 18 months, many organizations find themselves having to maintain multiple separate email domains. Existing solutions for this problem are capital- or administrator-intensive. Here we explore a simple solution that allows an organization to support arbitrarily many separate domain spaces on a single host machine with only a single Sendmail server. This system has been used in production at the author's organization since 1994 with great success.
