Harker Systems is proud to announce two seminars on sendmail:
"Sendmail Made Simple" which covers the operation of sendmail, sendmail.cf file,
	rewriting rules, and debugging of sendmail
"Advanced Sendmail & Electronic Mail Domains" covers setting up mail
	sub-domains, DNS and MX records, IDA sendmail, and creating sendmail.cf
	files using the Ease and m4 sendmail compiler
(Sendmail Made Simple is a prerequisite to Advanced Sendmail.)

The dates for the Sendmail seminars are as follows:
Austin, TX
	Sendmail Made Simple				February 8, 1993
	Advanced Sendmail & Electronic Mail Domains	February 9, 1993	

These Sendmail seminars are also being offered in:
Santa Clara, CA	
	Sendmail Made Simple				January 14, 1993
	Advanced Sendmail & Electronic Mail Domains	January 15, 1993
Los Angeles, CA (Manhattan Beach)
	Sendmail Made Simple				January 19, 1993
	Advanced Sendmail & Electronic Mail Domains	January 20, 1993
Seattle, WA
	Sendmail Made Simple				January 25, 1993
	Advanced Sendmail & Electronic Mail Domains	January 26, 1993

These seminars are aimed at the system administrator who would like to
understand how sendmail works and how to set up complex electronic mail domains
using sendmail.

The one-day Sendmail Made Simple seminar covers the topics of sendmail
operation, how to read the sendmail.cf file, how to modify the sendmail.cf file,
and how to debug the sendmail.cf file. A pair of simple sendmail.cf files for a
network of clients with a single UUCP mail gateway are presented. The SunOS
4.1.1, ULTIRX 4.2, HP-UX 8.0, and AIX 3.1 sendmail.cf files are discussed.

After this one day training seminar you will be able to:
Understand the operation of sendmail
Understand how sendmail works with mail and SMTP and UUCP
Understand the function and operation 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
Understand the operation of vendor specific sendmail.cf files
	SunOS 4.1.2, DEC Ultrix 4.2, HP-UX 8.0, IBM AIX 3.1

In the one-day Advanced Sendmail and Electronic Mail Domains seminar how mail
sub-domains work, configuration of mail sub-domains and mail routing hubs,
the purpose of Internet Mail eXchanger (MX) records, and setting up the Domain
Naming System (DNS) to advertise MX records for domains and sub-domains.
The Ease sendmail compiler, the m4 compiler for sendmail 5.65, IDA
sendmail, and UK-sendmail sendmail are explained.

After this one day training seminar you will be able to:
Understand the function and operation of sub-domains in a complex mail network
Understand how to set-up mail sub-domains and mail routing hubs
How mail delivery with-in the Internet is assisted with Mail eXchanger records
How to set-up the Domain Naming System on a firewall gateway to provide MX
	records for domains and internal sub-domains
How to create sendmail.cf files using the Ease and m4 sendmail compiler
How to use the m4 sendmail compiler with configurations from:
	sendmail 5.65, IDA sendmail, and UK-sendmail

An outline for both seminars is included at the end of this announcement

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