    Question [SOLVED] 8th grade student needs help with install

    Hey guys, I am incharge of a discovery learning technology course. One of our students has been trying to install zimbra and is stuck. He is using a fedora 5 box and the newest release of zimbra opensource. He has reinstalled zimbra over 10 times and always ends up with an MTA problem.

    Is there anyone in the zimbra community that might be willing to talk to the student. We have the ability to call any one in the US for free.

    Feel free to pm me with suggestions.

    Thanks

    Has he checked the forums for a solution, it's likely to be a simple error. The most common ones being DNS & host file configuration. Have him post his questions here.
    Regards

    Default DNS might be it.. it is a mystery to us

    Here is the typology of our network.. We have one router with a static IP from that we are forwarding port 80 to our IIS server to serve a web page. We followed the notes and forwarded all the necesary ports to the zimbra box like stmp, https, all of that stuff. We edited zimbra to make it host the web mail on port 81. When we log in zimbra now the mta is checked and now our spellcheckisnt working. However I dont care about fixing spell check at this moment. I would like to just get the mail working.

    I need to know what DNS configurations to make. Will I be actualy editing the DNS on the windows server? Or do i just make sure that the windows server ip is in the dns box under networking proporties for the card. Dns is confusing to me, and we have a DNS server for our windows domain (EASTLAB). Then we have the schools DNS, and lastyear while messing with the website stuff I remember having to have something reguarding dns done by the people who sold us our domain name. We have a valid domain name and one of those prefix names. www.mpseast.com and mail.mpseast.com they both point to our router.

    Right now the zimbrahost name is localhost.localdomain. I am wondering what I have to do to send and recieve mail as user@mpseast.com?

    Under the DNS tab in Network configuration we have :
    Hostname = localhost.localdomain
    Primary DNS = DNS server on our classroom network
    Secondary DNS= 65.64.8.3 known good dns in the town next to us
    Teritary DNS = blank
    DNS search path= localdomain


    thanks for the help.. I am sorry if I did not give you the information needed. We are totaly new at this.

    Are you ok with starting from scratch? -easier than changing your hostname
    (see all the troubles with changing your zimbrahostname here: ZmSetServerName - ZimbraWiki)

    Follow all the uninstall directions (UnInstall Zimbra - ZimbraWiki)
    Change your hostname (in that 'Under the DNS tab in Network configuration') to mail.mpseast.com & reboot

    your /etc/hosts file should look like
    127.0.0.1 localhost.localdomain localhost
    x.x.x.x.x mail.mpseast.com mail

    Then once your back up and running in zimbra admin console:
    So your email address isn't user@mail.mpseast.com you'll just create another domain 'mpseast.com' and make the new users there. You can easily (with a drop down) change what domain a user belongs too, but be careful with the admin account. (leave the mail.mpseast.com alone for now-it'll be setup to get admin emails etc)

    Now you don't have to do split dns -you could just not use external ip/resolution/ with your static public IP for everything.
    But you had said "DNS server on our classroom network" (what you would be doing instead of bind)
    Split DNS - ZimbraWiki
    /blog/archives/2007/06/making_zimbra_bind_work_together_1.html
    OR
    You send outbound mail through an existing server (if the school would allow you to connect)
    An alternative to setting up a DNS server is to un-check "Enable DNS Lookups" on the MTA tab under Server configuration on the Zimbra Admin console. This requires a relay MTA to be configured somewhere that will accept all outbound email.
    OR
    lastly, there's the zimbraMailTransport mapping attribute

    not your issue but for later there's also: Outgoing Mail Problems - ZimbraWiki

    Thank you mmorse. I have a student that is going to stay after school and attempt to figure it out. He was excited that you posted good valid resources. Some times knowing where to get valid info is more important than the answer its self.

    I appreciate the help, and I continue to have the student update the thread under my account.

    Thank you to everyone who is contributing. This really helps me teach the kids about professional resources.


    Thanks again

    Mike

    Sound's like you have good program there, and that's not even a HS or college!

    I had an excellent HS Application Technology department, and we would do the same type of things as your doing in my electronics & computer repair classes. However, the school was looking to save $ (it's easier to put in a bunch of desks for a 'standard subject' class...) and the year after I left a key teacher retired; after a good 25+years of teaching. While the two remaining faculty could keep up 'tech design' which had like 20 modules to rotate through; as hard as they try their still understaffed (and subsequently underfunded) so it got reduced from 4 electronics courses to just 1 level. (not talking quantity of kids, but the difficulty of the course) It's a catch 22 because once your forced to do that-it's hard to convince administration to find the funds to add another few faculty > so that you can increase the complexity of the courses, etc, etc...

    8th grade-think your the current winner for the 'youngest installer award' From our success stories section (actually the 1st post in that section):

    heh. well i would be lieing if i said no problems. my /etc/hosts file looked like this:

    127.0.0.1 localhost.localdomain localhost
    127.0.0.1 mail.mydomain.com mail

    i then changed the ip address of the mail.mydomain.com entry to the eth0 interface's ip address and everything worked fine.

    good stuff zimbra team

    Default Progress?

    So the back tick command gave me a "Command not found" error.
    But the mx command gave us this.

    ;; QUESTION SECTION:
    ;mail.mpseast.com. IN MX

    ;; ANSWER SECTION:
    mail.mpseast.com. 3600 IN MX 10 mail.mpseast.com.

    ;; AUTHORITY SECTION:
    mpseast.com. 19201 IN NS dns3.valueweb.com.
    mpseast.com. 19201 IN NS dns1.valueweb.com.
    mpseast.com. 19201 IN NS dns2.valueweb.com.

    ;; ADDITIONAL SECTION:
    mail.mpseast.com. 1609 IN A 170.211.174.36

    dns3.valueweb.com. 153700 IN A 207.36.174.5

    Both, Postfix and zmapchectl aren't running.

    Your external (what you posted) looks fine.

    Is the only IP assigned to the box 170.211.174.36? or do you have a private ip?-for which you need the machine to resolve lookups from the local dns (the bind articles or use the 2 dns boxes you already have) and get a private ip, usually like the below:
    10.0.0.0 - 10.255.255.255
    172.16.0.0 - 172.31.255.255
    192.168.0.0 - 192.168.255.255
    (assigned via dchp or manually set on every computer)

    170.211.174.36 = router ip (mpseast.com & mail.mpseast.com point to this ip)
    192.168.1.15 = linux box (zimbra box) ip
    192.168.1.2= Domain Controller/IIS/DNS

    So at this point everythingis correct, we just need to work on DNS? Should we load bind on the linux box or try to use the windows DNS? Which would be easier?

    Since the DNS on the windows network is already running wouldn't we just have to make some entry changes? Maybe set up a reverse lookup zone?

    Yup, if your able to manage the 192.168.1.2 DNS box, give it an entry for mail.mpseast.com pointing to 192.168.1.15

    on the zimbra box- make sure your /etc/resolv.conf (or just see dns settings in your GUI) are set to use the internal 192.168.1.2 box for dns lookups

    set your /etc/hosts to:
    127.0.0.1 localhost.localdomain localhost
    192.168.1.15 mail.mpseast.com mail

    /etc/hostname (or again use your gui):
    mail.mpseast.com

    if the hostname has changed/was different-easiest to just do a fresh uninstall/reinstall of zimbra (note: you shouldn't have the proxy (perdition) service installed at all on a single server setup)

    Once zimbra is fired up, be sure 'enable dns lookups' is check in both the server & global settings mta tabs (it probably will already be)

    These should return the private ip's:
    host -t mx domain
    or
    host `hostname` <-- backticks not single quotes

    Later on (well you might as well set this anyway)
    If you have trouble with outgoing mail & see some 554 'relay access denied' errors:
    zmprov gs server.domain.com | grep zimbraMtaMyNetworks
    zimbraMtaMyNetworks should have 127.0.0.0/8 192.168.1.0/24
