Hosting Multiple Mail Domains in SL server on a Mac Mini

So I have been trying to find out the answer to this question, and I keep getting conflicting information, and I am hoping someone here can help me solve this.
We are running two very small business with two different Domains (@company1 & @Company2) Each company has a website, and corporate email. All I want to do is bring all of this in-house onto one Mac Mini server. The calendars and contacts will be shared between the two principle owners of each company (my bosses) as they support each other in there individual business.
The Apple "Genius" says this is not possible, I believe and have been told by a few people and after reading posts on here that it is possible to have multiple domains on one Mac Mini Server. I would like to figure this out quickly as the companies have a need to move off the current email provider as fast as possible due to complications with iOS4 and the iPads.
Any Help from people who are doing this, or know it to be possible or impossible would be greatly appreciated!

This is entirely possible, and supported by the Server Admin user interface for the mail server.

Quoth the Book Of Mail:
A Mail Service Virtual Host
Virtual hosting is a method you can use to host more than one domain name on the same
computer and IP address, with overlapping mail user names.
For example, a mail server can receive mail transfer requests for two domains,
mail.example1.com and mail.example2.com, both of which resolve to the same IP
address. For mail.example1.com, the server delivers mail to “[email protected]
to a user mailbox for “bob,” while it also delivers mail to “[email protected]” to
a different user mailbox. Virtual hosts are essentially the converse of local host aliases.
One subtlety here is that the domains sharing the same mail server and all co-resident on the IP address will all tend to have the same public host name listed as their MX (mail exchange) server of record in the public DNS. This so that forward and reverse DNS and MX server all line up for the mail server for all the domains involved.

  • Hosting Multiple Mail Domains

    Hi There:
    I have some questions, will you please help me.
    My Server is set
    example.com
    I need to set additional / Multiple E-Mail Domains, these need to be separated, like:
    example1.com
    example2.com
    example3.com
    For the E-Mail Client, what will be de In-Comming Mail Server and Out-Going / SMTP
    mail.example1.com
    mail.example2.com
    mail.example3.com
    or it will be "mail.example.com" for all 4 Domains.
    I would like to say THANK YOU in advance

  • FileMaker Server problem on Mac Mini Server - Mac Mini won't boot

    I just installed a brand new Mac Mini Server today, and also FileMaker Server 11. A first-timer for both Mac OS X Server and FileMaker Server, I made an error as explained below, and right now I don't know how to get back on track with the system. It won't boot.
    So, how did this happen?
    At first everything was proceeding according to plan. I configured the pre-installed Mac OS X Server on the Mac Mini with users, groups and services. This was tested from clients and this seemed to work just fine. Then I installed and configured FileMaker Server. This was also tested from a client, and the example database that came with FMS was served up just fine.
    The problem arose when I tried to install my existing FileMaker databases. I simply checked to see where in the file system the example database was located, and then copied my old databases to that location (I think it was Library > FileMaker Server > Data > Databases or something close to it - can't check it now...). I had the FileMaker Server Admin Console running, and hit the Refresh button hoping that this would make FileMaker Server find the databases.
    This was my first error. I should have read ahead in the instructions to see that one is supposed to use an Upload Database assistant instead...
    What happened when I hit refresh was that the FileMaker Server Admin Console became completely unresponsive with a spinning ball as cursor. I left it for about an hour hoping it would terminate, but gave up and tried to shut it down. It wouldn't close, so I force quit it from the Finder. Then I tried to shut down FileMaker Server, but I needed to force quit this as well. After this I thought it would be best to reboot the Mac Mini, so I shut it down, but now it won't even boot, it just stays on the screen with the spinning wheel for ever!
    I have tried all the keyboard options while booting, but nothing seems to help. In safe mode, the grey progress bar just grows to about one third, then disappears and leaves the eternally spinning wheel.
    The server version of the Mac Mini doesn't have an optical drive, only two internal hard drives. I tried to reinstall from scratch using the optical drive on another Mac on the network. The startup disk appeared when I tried to boot the Mac Mini holding down the option key, and after about 20 minutes or so of the spinning wheel I could actually access the discs. I started by running Disk Utility to check disk permissions. There were a lot of repairs concerning permissions and groups, especially on "Library". It said "ACL differs on Library", I don't know what this is but this was repaired. I then ran Repair Disk. The volume appeared to be OK.
    When I tried to reinstall Mac OS X Server however, this failed with the message
    "You can't upgrade this version of Mac OS X because a newer version is installed. Mac OS X Server couldn't be installed on this disk." I don't know how this can be, but I may have run software update earlier today.
    What should I try next? Should I erase the primary HD and try to install again? Or should I install the system software on the secondary HD? Or should I just try to reboot as is in the hope that the disk permission repairs did the trick...?
    Any helpful pointers would be greatly appreciated!

    Hello there, I came across your post when browsing the forum for passive advice. I am in the same boat as you and am a first timer for both of these tools. I work for a company who now needs to expand its network and database capabilities. I have been assigned this task and these are the tools i have opted for. I have not yet purchased them and i am pleased to find someone who has my desired setup. Could you please advise on the simplicity of the setup and whether an advanced knowledge is required.
    I want to use it in a mixed operating system environment. Is this possible?
    Regards

  • How do I reinstall Snow Leopard Server on a Mac Mini Server 2010?

    How do I reinstall Snow Leopard Server on a Mac Mini Server 2010? I have already attached a Mac Superdrive and tried to download, but the buttons at the bottom of the dialog screen are greyed out.

    Not sure where you're getting tangled here or how much you know about OS X Server 10.6, so...
    AFAIK, Snow Leopard Server wasm't available as a download, it was a separate DVD distribution. 
    Unlike more recent versions of OS X Server, the 10.6 server distributions were usually standalone DVD disks, as well. 
    (There is a slight wrinkle if your Mac needs a newer version of 10.6 than your server distribution; there was a different streaming upgrade process for that.  IIRC, the appropriate OS X client version was installed first, then you booted that client version and loaded the DVD and installed OS X Server.)
    But if you have a Snow Leopard Server distribution that supports your particular Mac Mini model, then boot the DVD, use Disk Utility from the Utilities menu in the bootable DVD environment, wipe the disk, and then install OS X Server.
    You'll need a 10.6 license key, if you don't already have that.
    FWIW, here are the available manuals.

  • Trying to install Leopard server on my Mac mini

    I'm a registered Apple Select Developer and I'm trying to install Leopard Server on a Mac mini I just picked up the other day. Is there a way to do this using the image or do I have to burn a DVD in order to do the install? The image is over 5GB's so I'd need to get a dual layer disk.

    Is this just for a test?
    If so you can create 3 partitions, one a bootable volume the second partition a place to restore the Leopard image and the third partition to install the new software you restored on the second partition. You do loose two small volumes temporarily, but you can make them relatively small since these are only used for installation purposes. The details can be found on the developer site under " leopardclient_9a377a_seednote.rtf".
    I've done this on older machines with no CD players installed.

  • OS X Lion or Lion Server on the Mac mini server?

    Can you choose to run OS X Lion or Lion Server on the Mac mini server?

    This may sound stupid and obvious, but can't you "borrow" a keyboard/mouse from another machine to do the setup?
    I'm not familiar with the server version of the software, but if it runs as soon as your machine starts up without having to select a "user" and/or input a password, then you should be able to do what you need to do remotely from another machine.  In the Finder, use the "Go" drop down menu at the top of the screen and select "Go to Server".  When that opens, "browse" for your new Mini and if it appears, connect to it (hopefully as a user rather than a "guest").  You should then be able to open any file including the "server application".
    I think if you have a laptop or other machine with no detachable keyboard/mouse to "borrow", you may be able to get it into close enough proximity to the new Mini to connect them via Firewire (if both have Firewire 800 ports) and work with the Mini in "target disk mode":  http://support.apple.com/kb/ht1661

  • Mac OS X Server, High Availability, Mac Mini

    Hi All,
    Currently running Mac OS X Server on a mac mini, I'm looking for some ways to make that mac mini "server" a high availability system for my office.
    The first thing i will change is to install the operating system on a external firewire 2 disks RAID 1 hard drive : http://www.lacie.com/us/products/product.htm?pid=10967
    Then I'm thinking how to make sure the rest of the mac mini will be running all the time as well.
    That's why I'm wondering if it's possible to make everything double : 2 minis with 1 RAID hard drive each.
    Each complete set would be linked to create somewhat of fail-over system : If one set woes the other one can take over with exactly the same data.
    A bit like what it's been done here :
    http://homepage.mac.com/pauljlucas/personal/macmini/cluster.html but with OS X Server instead of Linux.

    Hi lulu62-
    I am working on a similar project with Minis so I will be keeping an eye on your site.
    In addition to Camelot's suggestions, do not forget to have a robust UPS with Automatic Voltage Regulation capable of supporting all of your gear for any expected down time.
    The Mini is excellent because you can power it for a long time on a healthy-sized UPS.
    Luck-

  • OS X Server install on Mac Mini.

    Hi,
    I"m looking to do a clean install of OS X Server on my Mac Mini. Wanted to get some input on how to best partition and setup my hard drives. For now server will be mostly used as a fileserver, music/video streaming. I may eventually start playing around with ical server, etc.
    Mac Mini ,2.53 Ghz Intel Core 2 Duo,dual 500 GB drives, 4 Gb memory
    1.5 Tb external Firewire drive.
    1.5 Tb external USB drive - data backup using Time Machine
    I was thinking about the following:
    Setup 100 Gb partition on each drive and turn on RAID mirroring, install OS X on that partition. Remaining space on those drives will be used as individual partitions for data.
    Install OS X on firewire drive and backup OS partition once installed. Can I get away with using Disk Utility or should I use other software?
    Thanks!

    I use Carbon Copy Cloner, Synchronize! Pro X, and Time Machine. I no longer use any of the myriad of other backup schemes that have not worked as well for me over the years.
    When I first get a machine, the first thing I do is assign a new large capacity backup for that machine.
    So :
    ( 1 ) I buy something like a 1 TB backup drive, select it at the finder level (hit return to put its name in the edit mode) and rename it something like NewBackupDrive.
    ( 2 ) use CCC to make a bootable backup from Macintosh HD ---> NewBackupDrive
    ( 3 ) boot from the NewBackupDrive to make sure it is working
    ( 4 ) Now we can partition the main internal drive Macintosh HD
    My last iMac came with a 640 GB drive, so when I used Disk Utility, and selected 6 partitions, it neatly worked out that the size of each partition was 106.69 GB, which for my needs was perfect. This gave me plenty of expansion capacity. You can adjust to fewer partitions if you need more capacity for each partition. Once you partition, write down the size of each partition, so you can partition the backup drive similarly.
    Using Disk Utility I select six and name them as follows. I dont use spaces on any directories that I might need to use the Terminal with, since it makes it easier using unix without dealing with spaces in paths.
    Drive_1
    Drive_2
    Drive_3
    Drive_4
    Drive_5
    Drive_6
    ( 5 ) use CCC to make a bootable backup of NewBackupDrive ---> Drive_1
    ( 6 ) use CCC to make a bootable backup of NewBackupDrive ---> Drive_6 (redundant, but good),
    this way over the coming days, or weeks, as I begin rotating backups from
    Drive_1 ---> Drive_2
    Drive_1 ---> Drive_3
    Drive_1 ---> Drive_4
    Drive_1 ---> Drive_5
    it will be last one over-written. Once you get to (Drive_1 ---> Drive_6), you can choose to use it, or skip over it and leave it pristine if you wish. Anyway for now, I would protect myself by doing steps ( 5 ) and ( 6 )
    ( 7 ) Boot from Drive_1, set your preferences, install any applications you will need,copy whatever you need and get the primary drive for the most part fully loaded with your data, so that it is fully functional.
    ( 8 ) Armed with the sizes of the partitions (should be one size if you made all partitions the same size), we can run Disk Utility, and partition to the same number of partitions as the main drive plus one. In my case that makes the number of partitions seven. The last one will be much larger and used for Time Machine.
    In my case the first six partitons will be 106.69 GB, leaving 358.86 GB tor TM_1 which is the Time Machine partition.
    Max_1
    Max_2
    Max_3
    Max_4
    Max_5
    Max_6
    TM_1
    In my case I use a Guardian Maximus (raid level 0) with dual 1 Terabyte disks that do hardware level redundant backups. If one disk dies, the other one will continue working, the diagnostic lights will warn you to replace the faulty disk, and when you place the new disk in the slot, it will automatically be backed up by the good disk. I will become a mirror image of the good disk...
    I have used many schemes over the years, including databases, spreadsheets, etc. What I use now is a simple notebook that I keep with each of the workstations, and servers that basically show the following :
    CCC 2010.09.08 Drive_1 ---> TM_4 Upgraded to OS X Server 10.7.4
    CCC 2010.09.08 Drive_1 ---> Drive_4 Upgraded to OS X Server 10.7.4
    CCC 2010.09.15 Drive_1 ---> TM_5 Completely Rearranged the Web Server Structure
    CCC 2010.09.15 Drive_1 ---> Drive_5 Upgraded to OS X Server 10.7.43
    SyncProX 2010.09.15 Drive_1/Server ---> TM_1/Server
    Best of Luck...

  • What's the purpose of OSX Server on a Mac Mini?

    What's the purpose of OSX Server on a Mac Mini? Is it to make it a Media server?
    Thanks,
    Jeff

    Mac Mini makes a good workgroup server, classroom server, web server, DNS server, authentication server, or... Pretty much any time you want a small and quiet computer for a particular task. And for typical tasks (web and DNS and...) you can roll several together onto a single box, and can run (for instance) two as paired DNS and Open Directory servers.
    Mac OS X Server works nicely on most any of the Mac Mini boxes, too, while the Mac Mini Server does have a better price here and a configuration that's more targeted at server-oriented uses. The MMS adds RAID in particular, though that could be added onto the previous servers using external storage and FireWire.
    If you want a media server, then you don't necessarily need Mac OS X Server, you can do nicely with Mac OS X client and connections to whatever you want to use for media; digital TV or whatever. Front Row works OK here, and EyeTV is very nice.

  • Reinstalling apple's snow leopard server on a mac mini

    Hello,
    I need to reinstall snow leopard server on the mac mini (the one without the dvd drive), and I bought an external dvd drive. How do I get the mini to recognize the external? I can't seem to get that option.
    Thanks.

    Plug the drive in and when you power up the mini, hold the c button on the computer keyboard while it boots with the restore disk in the dvd drive. After a minute or two, the computer will start from the dvd.

  • Wiki Server support on Mac Mini with Snow Leopard?

    Hi
    I am considering buying Mac Mini with Snow Leopard server. Before that, I want to know about wiki server 2 capabilities. Wiki Server 2 page says following:
    "Mac OS X Server makes it easy for groups to collaborate and communicate through their own wiki-powered intranet website complete with group calendar, blog, and mailing list"
    I am planning to setup wiki server for a small group of users over Internet (and not intranet) to exchange information and so it should look something like wiki.mydomain.com with login capabilities for user(and again, this is over internet).
    My Question: Can wiki server 2 work with web server to support above (or similar) setup?
    If not, what can be done to support above setup?
    Response appreciated.
    Thanks in Advance.

    The new Mac mini comes in three different configurations, two of those have the standard version of Snow Leopard.
    There is an article that addresses issues similar to this here: http://support.apple.com/kb/HT2186, but switching from Snow Leopard Server to Snow Leopard is not like trying to install Tiger when the Mac mini came with Snow Leopard.

  • I transferred files from a NAS server to the Mac Mini Snow Leopard Server and now some of the files have Custom Access and can't  be opened by some users.  How do I fix this?

    We're setting up our Mac Mini Snow Leopard Server, and in the process transferred files that had been stored and accessed from our Blackarmor NAS server over to the Mac.  These files were all created on PC's and are Office Excel files, WordPerfect files or PDF's.  When you look at the files on the Mac from the Mac and bring up Get Info for the affected file, it says that the file has Custom Access.  The files that work properly don't have that configuration.  I can access and open the files on some computers, but some users can't open the files from their computer even though they can see it.  We're all using PC's and they get the Error:  Access Denied-Contact your administrator--or something similar.  I've seen on the web similar issues and it may have something to do with ACL permissions.  I don't know enough about Mac OS to understand this, but what is baffling is that they can be opened from some PC's but not others, and all of the Users have the same accessibility to the files.  Thanks for a solution!!
