Introduction

This is a set of HTML slides for a presentation I gave in August 1997 to my local System Administrators Guild (SAGE, or SAGE-AU for fellow Australians).

The subject was migrating Mail Transport Agent (MTA). Some of the examples are now dated; qmail particularly has improved compatibility with sendmail since then, via updated documentation and a new utility or two.

See http://www.qmail.org for up to date qmail information.
