The one-day Sendmail Made Simple seminar is designed for the UNIX mail
administrator who needs to know how to configure and debug sendmail for a
network of UNIX hosts which exchange mail with the UUCP/Internet mail
network.  You will learn how to register and setup an Internet mail domain
for their organization.  A set of simple sendmail.cf files for a network of
clients with mail gateways are presented to explain configuration of sendmail

After this one day training seminar you will be able to:
* Install and configure sendmail and sendmail.cf for your site
* Understand how sendmail works with mail, SMTP, and UUCP
* Work with UUCP service providers to create an Internet mail domain
* Understand the function and configuration of sendmail.cf files
* Create custom sendmail rewriting rules to handle delivery
	to special addresses and mailers
* Debug mail addressing and delivery problems
* Debug sendmail.cf configuration files
* Use and install vendor specific sendmail.cf files:
	SunOS, DEC Ultrix, HP-UX, IBM AIX


The one-day Advanced Sendmail and Electronic Mail Domains seminar is designed
for administrators of complex electronic mail networks who need to know how
to design, setup and manage mail sub-domains.  You will learn how to setup
sendmail and the Domain Naming System (DNS) on a mail gateway which relays
mail with the Internet.  You will learn the advantages of using IDA sendmail.

After this one day training seminar you will be able to:
* Understand how to use sub-domains in a complex mail network
* Set-up mail sub-domains and mail routing hubs
* Understand how mail delivery within the Internet and to sub-domains
	is assisted with DNS Mail eXchanger records
* Set-up the Domain Naming System on a firewall gateway to provide MX records
	for domains and internal sub-domains
* Use and install IDA sendmail
* Create sendmail.cf files using the m4 sendmail compiler and Ease

Course Fees: US$349 either day, US$675 both days.
Fees include the seminar, seminar notes, lunch, and refreshments.
