Well here is the list of mail server software for people to check out.
http://en.wikipedia.org/wiki/Comparison_of_mail_servers
And Bryan, I'm not trying to flame you, but I think your argument, points
out exactly why Exchange is not the way to go. I understand you're happy
with it, and it works for you, I'm not trying to make you change it.
But $1500 ?, Is that just the cost of exchange ? What about the Box, and all
the other programs you are citing to help maintain it, and the licenses for
each of those programs based on 70 users. That's $2800 for outlook alone.
You can design mail systems to accomplish all these tasks via linux or MS,
and they will both work, but when it comes down to it, MS will always be a
proprietary system and will cost more to implement.
On the Linux side you can go all free, or mix and match, sure you may have
to configure more programs.
But once you have a solution working on both sides, it is always going to
cost more to add a user on the MS side than on the linux side.
Like I said before, we don't have a performance benchmark, to even compare.
Why don't we come up with a list, of what features are required for a stand
alone mail server, and compare MS vs Linux solutions, and then compare the
prices of those components. Maybe for a 20 user, 100 user, 500 user system.

Craig, I think you are missing the point. So, not to call you out on the
carpet here but have you ever managed a large enterprise? If so could you
please explain your ideal concept of how you manage to keep productivity
high and cost low without use of any non-free or non-open products? Take
Asterisk for example. I love it but the total cost of ownership is
outrageously high in comparison to systems like Avaya and ShoreTel. And
that is without the incredible ease of integration of systems like ShoreTel
have with outlook. You bag on Exchange but offer no comparative substitute.
You complain about the fact it uses AD and how much it costs even though it
is included free in several flavors of Exchange distribution. You complain
about mailbox implementation but seem to think it is the only DB your
company would be running. How do you back up your Oracle, MySQL, DB2, or
Postges systems? And again with the scanning, it provides it's own free
scanning system, however it is idiotic to be dinging the bulk of your spam
scanning on the mail server. By the time it reaches your server the cost of
resources expended to handle it far outweigh the cost of third party
scanning. And the fact that Third party AV scans can be integrated easily
is not a bad thing, saying so is like saying postfix sucks because you can
use spamassisen and calmav. In fact I can use clamAV but it does not
provide the same level of service for the same maintenance cost of better
products like Avast. That said you say the only client is outlook, so my
question is what server/client system do you have that provides anywhere
near as much to the party as exchange/outlook? If you have one I would
really, really, love to try it out! But I have not found one. Certainly
Cyrus is not it. And for cost I can put an exchange system in for a 70
person office with all the clients and servers licensed from scratch with AD
and everything, including the server and my time to set it up for less then
$1500. In addition each users outlook costs only $40 and that also includes
all the other MS bundled stuff we have not talked about (Share point, etc.).
And while there are far better solutions for nearly all of it (especially MS
SQL Server) Tell me now. Can you purchase a server, provide a integrated
collaborative PIM suite in a single interface providing mail, contacts,
basic CRM, takes, notes, and journal com tracking for the same price? If so
I really would like to see it because I have bee hunting for this for almost
10 years! I hold fast that Exchange is one of very, very few MS products
that has a very high ROI. And, have you every had to integrate a BES with
something other then Exchange? Or are you some one who has never managed
more then a handful of mobile devices.
Now if you're a single person or a company of 5 it is stupid to implement
exchange. Use Google. If you're a fleet of sales people who never talk to
each other and have an independent sales management application, then again,
Exchange is not your option, but for most small campus based businesses that
employ a group of average people who need to communicate easily with their
teams exchange is your answer. In the real world your business needs and
the bottom line dictate the solution, not your personal feelings. And time
and time again, for medium business after medium business, Exchange has
provided. If you really want we can conger up an average small company
prototype and each deliver a robust communications plan. But I think your
average CFP will pick the exchange plan every time.
And yes one of my three home computers is MS, and yes I run outlook on it
(Evolution and thunderbird on the other two) But Outlook is my primary PIM.
I find on lists like this I have the fringe voice of pay/proprietary
software, just like in the business world I am the fringe voice of free and
open source. So, I get flamed from both sides.

this is absurd - once you have used cyrus-imapd and all of the e-mails are
separate files you realize how antiquated and stupid the concept of an
Exchange mail store is. Oh, you can buy programs with Exchange 'agents' to
allow you to back up live or you can use some routine to shut down Exchange
to allow a backup but it's clearly a hostile environment, much like backing
up any database.

I think you just made my point...buying specialized software add-ons to
perform scanning - and of course, the 'Exchange Server' options.

good webmail is easily implemented as are LDAP client applications. OWA is

My point seemed to be rather obvious. You're in for the penny, you're in for
the pound. The issue isn't about whether Linux or Macintosh can integrate
into an AD environment...of course they can.
The issue was about buying in and having AD dictate everything from user
accounts to machine access and all resource management. To use Exchange, you
have no choice other than to go the whole hog...there was no other options
after Exchange 5.5
The simple truth is that Microsoft didn't create the Enterprise environment
nor do they possess the only logical implementation. They have the marketing
muscle and the foresight to create artificial dependencies to use software
to dictate implementation.
Start tossing in curveballs such as IP Telephony integration and it becomes
a major clusterf**k.
The ultimate issue is that the only decent client for Exchange is Outlook
and thus the only decent OS to use is Windows and thus the vendor lock-in is
full circle.
Clearly as businesses tighten their belts, the costs of license 6 or just
generally the various licenses necessary to be purchased for client access,
whether to files or to Exchange Server or to MS-SQL server get to be absurd.
As few businesses have embraced the move to Vista, Linux options for the
desktop continue to improve and Exchange Server will see its value
declining.
