I've been tasked to move my company's email from exchange to linux/sendmail.
I'm new to linux and sendmail and need some . Our exchange 5.5 is
running the Internet Mail service and the clients use Outlook. We also have
our own dns server on a nt4 domain. We bought suse es9 and I'm getting to
know linux. What do I need from linux and/or sendmail(as far as
authentication/client software) for this migration to succeed. If someone
can point me in the right direction, I can do the rest. Any would be
much appreciated, tia.

You also need software to run a pop3 server, an imap server, a webmail
server.

You need to create all the account needed on the server for your users
and you need a way to manage all those accounts conveniently.

You may need to be able to tie in the server to an external directory.

You need to consider which milters for antivirus and spam control you
want to run.

You may want to go the courier route.

Or you can use sendmail with popular servers like qpopper and uw-imapd
and squirellmail or horde (which will involve apache/php setup)

I suggest you print out all documentation that comes in the sendmail
sources as found on sendmail.org and all documentation on your chosen
servers and buy the bat book as well.

Take a look at the linux documentation project. You should probably get
the running linux book.

You especialy want to pay attention to your alias setup, your
virtusertable setup.

Pay some attention to SMTP auth and make sure your server supports
starttls.

You can manage users manually in the old unix tradition, with the new
graphical tools provided by the distribution, from webmin, with a
script, open-source-off-the-web tools or roll your own.

With a little bit of hunting you could probably find an entire package
that does all this for you on unix/linux.

Sendmail only transfers email from one host to another. It does not
have anything to do with authentication.
You need to create all the user accounts in the sendmail server
manually. I wouldn't know how to synchronize Unix users with a domain
controller.
Then you need to install imap and/or pop3 server software. There are
many options for those. If you have limited experience, I suggest you
use Qpopper for pop3 and UW-Imap for imap since these are not too hard
to get working.

Did anyone plan this out first?

As others have noted, Sendmail itself does not do everything Exchange
does. You'll need one or both of a POP3 server and an IMAP server, maybe
a webmail package, and maybe a calendaring system.

I'm a fan of Dovecot for POP3 and IMAP. I don't bother with webmail, and
where I work with mail-connected calendaring it is nothing like what
Exchange offers: all calendars are local to the user and not shared.

Good luck.

Seconded, I'd take a serious look at phpgroupware:

http://www.phpgroupware.org/

Or others in the line, which should be the easiest to get all
features the OP has now and some more. A search on freshmeat.net
should offer other packages in the lines.
