Suse open exchange

Hello I have a client that has a exchange server 5.5 that they hate :) I have install suse open exchange, and it is up and running. I have added all teh users, but besides that have made no more configuration changes. If I change the ip pf the suse box to the ip of the exchange box, and take the exchange offline will it just start working? everyting in the world is setup to the firewall, and pointing to that ip? I know I have to setup the clients through outlook? please help?

Hi eberhardt2329,
Yes it should just work. You will probably also have to use the web interface to edit its own entry in its DNS.

A few tips for using openexchange :-

1) After installing immediatly run an automatic internet update as the initial install has a few things which are broken.

2) In the postfix configuration enable the 'local recipient maps' otherwise all email will be accepted and then bounce messages sent back for mail to nonexistant users which just fills up your mail queue. Enabling the locla recipient maps (which is the postfix default) causes incoming mail to be rejected if the user does not exist.

3) If you are going to use spamassassin for spam filtering edit the entry in the sysconfig directory and remove the '-L' option to enable DNS lookups as it makes it far more effective.

4) Dont bother about paying for their antivirus solution. Install amavisd-new and clamav instead. It is completely free and works very well.

question how do i do the postfix, and what change to dns do I make?
0
 
grbladesCommented:
It's all done through the web interface. Just login as 'cyrus' which is the mail administrator account.
There are menu items for DNS administration and advanced mail server configuration. Just tick the 'uncomment' box next the the 'local recipient maps' entry.

What is the full hostname of the openexchange server?
It should have been setup with the same full name that you have listed in your DNS MX entries where mail is delivered to.
All you really need to do at this time is if you change the IP address you need to update its own hostname in the DNS with its new IP address.

You also need to make sure the computer advertises the correct hostname when sending email and this is correctly configured on the Internet DNS servers to avoid problems with email being clasified as spam.

i am sorry I was going through the web interface I went the the server, and logged in as cyrus, but now it is saying that kde can not start because it can not write to home what does this mean?
0
 
grbladesCommented:
'cyrus' is not a real unix user so it does not have a home directory etc... Just OK any error messages and log out. If you need to log into the console to run updates etc... you need to log in as 'root'.

eberhardt2329Author Commented:
oh ok I will do that, I am sorry, and I really appreciate the help, I know how hard it is to work with someone that does not know something. I will logon as root, and try to get the info for you from above

Is it a brand new installation of openexchange?
It sounds as if you might not have logged into KDE as root and run the software update tool to download all the updates. When you have done this do a reboot.
Have you sent your redistration off to Suse and received back a serial code?
Without this you will be limited to only 10 groupware users logged in at a time.

they only have 5 7 people that work here, It is a new install of open exchange, how do I run the software update tool on the server, I will do this, as soon as I hear back from you thank you so much
0
 
grbladesCommented:
If you log into KDE as root there are a row of buttons along the bottom. Second button from the left brings up a menu. Go into the software one (cant remember the exact name) and choose the online update. You will need a valid username and password so if you have not done so already you will have to create yourself an account on the suse website and enter your registration details.

will I have to pay, they do not want to pay for this, do they have to? if they do is there a site that tells you this? I am really new to this product. I also went on the bottom row, the second button over, and the only options are install or remove software, or install software package?
0
 
grbladesCommented:
It is commercial software so you do have to pay for it. You have to provide the registration details to get a username/password for the update and without running this it is not really usable to be honest as the initial release had many bugs.

they downloaded open exchange 4.1, and they were presented with a cost of 500.00 witch they were ok with, but then novell upped the price to 1300, if they need to buy it I need to know why, so that I can present this to them, thankl you

eberhardt2329Author Commented:
is there a list of bugs with the release a website that tells me why I need the updates, I get this I will give you the points, and create a new question hopefully get you again, and when they buy it resolve the other issues

grbladesCommented:
Although the OS is itself free they charge for the groupware (shared calendar etc...) and the system comes with 10 clients as standard so effectivly you get 10 clients so you have to pay to use it. You also get the 1st years maintenance free. You need to pay to get an update username/password and until you do the first automatic update it is very unreliable.

If you just wanted it for email and not bothered about the calendar and contacts then you could configure your own mail server for free but if you are new to Linux this will be a steep learning curve.

eberhardt2329Author Commented:
is there a site explanning the bugs in the release? This would help be explain to them why they need to purchase it. you said the first year of maintenance is free you get this if you do not buy the product?
0
 
grbladesCommented:
There is no list of bugs but when I tried using it initially the web interface was almost unusable. There have also been many security updates including ones for apache and ssl so without the updates your mail server could be vulnerable.

If you don't purchase it you are not permitted to use it basically.

grbladesCommented:
I didn't know you could download it. I think it is there incase you get a damaged CD for example or loose one.
