Migrating FROM Gmail to 10.6 Mail server

I am in the process of setting up a new 10.6 Server to be used for internal Mail, iChat, iCal, Wiki, & File Sharing. We are currently using Gmail for all email.
Can anyone recommend the best way to move all current emails in each account on Gmail to the SL Server that I am setting up possibly in a manner that involves as little downtime as possible?
Each user (around 45 of them) with the exception of five Mac users in the company who use Mail, are all using Gmail's web interface. I have thought about installing an email client (all using win xp or vista) using IMAP and DL all emails to their computer, but this leaves the only copy of that email on that computer system, and would be a pain when their station has to be switched out for any reason to move the emails to the new system. Recommendations?

That you're asking this question is somewhat concerning.
Depending on the tool (and in the typical case), you're transferring messages directly from one mail server to another mail server.
Actually, since this is the first Mac OS X server, and mail server at that matter, that I have set up, I do believe that this is a valid question, and shouldn't be alarming one bit. I have not yet turned on the mail server, nor have I begun to delve into all of the documentation yet, as the mail server is the last part to implement.
Presuming imapsync, you're using a tool that pretends to be a mail client to two different mail servers in parallel; it pulls down messages from one and synchronizes those messages directly to another server.
For another document on the imapsync tool, here is the [imapsync readme|http://www.linux-france.org/prj/imapsync/README] via [Freshmeat|http://freshmeat.net/projects/imapsync>
Thank you for the direction to some more documentation on imapsync!

Migration from gmail to office 365 mail box.

Recently, I migrated gmail to office 365.
After I migrated to office 365, outlooks mail box size is almost double of gmail mail box.
ex: One of the user had 26gb data in gmail , aft the migration his exchange online mailbox became 46 gb.
any ideas?
Sutha Thavaratnarajah

Both Office 365 and Gmail uses different systems. Sometimes its normal that size of the mailbox to increase after migration. But in this case its too high so I request you to check for Folder named GMAIL
in the user's Mailbox

Calendar Server Migration from iplanet5.2 to Sunjava messaging server

Hi
Can any one help me on Calendar server migration.
How can i migrate the calendar server from iplanet 5.2 to sunjava messaging server

Hi,
I assume you mean iplanet calendar server 5.1.1 to the latest calendar server (6.3). If so, I suggest you start by reading through the calendar server admin guide which goes through the steps involved and tools to use to migrate from 5.1.1 onto calendar server 6.3.

Junk and Trash mailboxes from Gmail disappeared on Mac Mail--any ideas?

Junk and Trash mailboxes from Gmail disappeared on Mac Mail--any ideas?
Under Mailboxes in Mac Mail, I used to see Inbox (along with sub-Inboxes for each account, all of which are still there), VIPs (still there), Sent (still there), Drafts, Junk and Trash, all of which are missing, without me making ANY changes anywhere, either on Mac Mail or Gmail.
Any ideas ... or other people experiencing same issue? (Happened in my wife's account and I just assumed the kids deleted something, but then I went to my account where the kids never are and I found the same issue.)

Do you mean that they are not listed under Gmail's header at the bottom of the Mailbox List or that they don't exist in the Unified Mailboxes at the top?
If they are not in the unified mailboxes, check down under Gmail and vice versa. If they are at the bottom under Gmail, select each separately and go to the Use Mailbox for command in the Mailbox menu. Set each one to what they are supposed to be, ie Trash, Junk, Sent, Drafts.
If they don't appear anywhere, log into Google's email website, go to Settings, click on the Labels tab and make sure those mailboxes are set to show in IMAP.
Finally, if they are IMAP accounts, just delete the accounts from Mail then re-add them. If you have a lot of email, it will take a while to synchronize, but it should recover those foldrs. If you are using POP, I'm not exactly sure how to save the old email, but I would assume Google is already doing that for you.

How do you mark a message as spam when your mail comes from gmail via OS X Mail.app?

How do you mark a message as spam when your mail comes from gmail via OS X Mail.app?
I use IMAP to get Gmail. I seem to remember seeing a "[Gmail]/Spam" IMAP folder in previous versions of the app, but that's not visible any more.
Without this, I have to log on to the web-based Gmail to mark messages as spam, that's a productivity killer.

right mouse click on a message and select Mark as Junk Mail

Migrating from Gmail to Hosted Exchange / Outlook 2010

My company has been using Gmail for its email for the last 5 years.
We were sharing a single company wide email address for 3 users. All incoming mail came [email protected].
Gmail let us create our own signature to the outgoing mail and the world was OK.
Everyone saw everything; anybody could tackle any issue or contact whoever was needed to keep things rolling smoothly.
Over 5 years our email spool grew HUGE.
As the company grew we have come against a few problems.
1. No privacy. The owners of the company have to use personal email accounts to talk about anything they don’t want the rest of the company to hear.
2. We recently started bringing in outside help to work on "special projects" and company information (past and present) and individual privacy is now important.
So I suggested switching from Gmail web based email to Outlook/Hosted Exchange.
Migrating our mail system was horrible, but I got it done in about 5 days over the 4<sup>th</sup> of July long weekend.
What I ended up doing is creating a user called EVERYONE.
I moved everything from Gmail into that account. I retained the directory structure we created in Gmail that has 100’s and 100’s of folders and subfolders.
I let (almost) everyone share that EVERYONE user.
Everybody also has a [email protected] email address.
When new mail comes in it get delivered [email protected], each person then sorts the message into our EVERYONE user account under
the proper project folder / subfolder / sub-category. This system works OK but I am sure there is an easier way, BUT THAT IS NOT WHY I AM WRITING.
MY PROBLEMS ARE:
Because we are using the old project folder granular Gmail file system it is difficult to move mail into the proper folders.
When we were using Gmail you would start typing the project name / subcategory and it would POP UP and you would drop the mail.
A typical folder nesting would be: ACTIVE PROJECTS->Jones Residence -> Sub-Contractors->Painting-> Master Bath->Wallpaper Samples
OUTLOOK does not let you move mail through a contextual system.
You have to “Drag and Drop”, but navigating through 5 or 6 folders and subfolders over and over is a PITA and my users want something similar to the Gmail system.
Ceptara's Organizer for Outlook and QuickFile for Outlook available on Slipstick look like 2 possible solutions.
Has anyone used either program?
How well did they do what I outlined here? Any other suggestions?
Thanks in Advance,
Kevin

Migration from MS Exchange 2003 to Mavericks Server

Can anyone recommend a migration path from MS Exchange 2003 to OS X Mavericks Server? The key features to be migrated and used with the new server are: email, contacts, calendar, group tasks management, file sharing.
Also, any hardware recommendation? Is Mac mini enough for a group of about 6-8 other Macs or could we benefit from the new Mac Pro? Perhaps an iMac (with a Fusion Drive)?
Thanks for any suggestions.

I don't think you know the limitations — Exchange Server provides rather more than what Postfix and Dovecot do.
This is a generic Exchange Server to Postfix/Dovecot migration, which — in conjunction with the imapsync option — might find some other discussions.
For migrating from Exchange Server itself, AFAIK, no, there are no packaged tools for that available. Tools such as imapsync can be used to migrate mail among imap servers, which can be an option here once imap is enabled on the Exchange Server, and once you know (or reset) all the passwords. Or you can select all and then drag and drop the messages.
Slightly closer to Exchange Server in capabilities are the Zimbra and Kerio products. Zimbra has migration tools, IIRC.
FWIW, please do not thread-jack, it just confuses the discussions — or at least it usually just ends up confusing readers. This is a very different question from the original, and should be its own separate thread.

Migrating from Snow Leopard to Mountain Lion Server

Hi all. I kinda drop in and out of this forum, mostly when I've got a puzzler that I can't figure out. My journey from Snow Leopard to Mountain Lion was a little slow. I tried to make the transition from Snow Leopard to Lion and failed, but this time I made it and I thought I'd share a little scratchpad post I wrote to document what I did. Mostly this is about adding back a few things that I really need. Here's the list of stuff that I added back:
Firewall management (IceFloor)
MySQL
Webmail, email filtering rules and email aliases (RoundCube)
"Group" emails (short, multi-recipient email exploders)
Mailing lists (Mailman)
I also dramatically improved reliability by adding a lot of memory, and doing nightly-restarts of the machine.
Here's a link to the post
http://www.haven2.com/index.php/archives/migrating-from-snow-leopard-server-to-o sx-server-mountain-lion
I'm happy to report that the new server has been running for a month or so and all seems fine. Whew. A long journey. Thanks to all of you who posted things that helped me along the way. Hopefully this will return the favor.

Moving from Snow Leopard to Mountain Lion means first installing the client (non-Server) version of Mountain Lion and then install Server.app this means that for at least part of the process you will not be running DNS, DHCP or Open Directory.
If you are going to end up using the same DNS name and IP address after the change then an approach you could follow would be as follows.
Destroy any Open Directory replicas
Archive your Open Directory Master (to make a backup)
Note down your DNS records in case they get messed up
Export via Workgroup Manager your users, and groups (you might not need this but better safe than sorry), make sure you do not include the diradmin account
Keep a full back of the server (you should always have backups)
Note down your DHCP server settings in case they get messed up
Note down any other service settings
Install Mountain Lion
Install Server.app
Install Workgroup Manager (extra free download)
Run Server.app
Make sure settings for services are as much as possible the same as before
If your lucky that may be all you need to do, otherwise...
Restore Open Directory archive, if your lucky that will be all you need to do, otherwise...
Make new Open Directory Master
Run Workgroup Manager
Import users and groups you previously exported
You will then have to set passwords for each user as these are not preserved via Workgroup Manager export
When I did this, I was also being forced to change all my IP addresses so I had no choice but to use Workgroup Manager to export and import accounts.

Migration from G5 to Xserve, 10.3 server to 10.4 server

I am planning a move from a dp G5 tower to a newer Xserve G5, and migrating the 10.3 server to the new 10.4 server. This is our main DNS, mail, web, and ftp server. It is currently running 10.3.8 and running a Netnfo db. I am looking for some strategy tips and practical suggestions.
I have read the migration guide. And while it is excellent, it is lacking in some crucial details. It is hard to believe that it doesn't mention changing IPs with changeip or networksetup, or deal with scenarios like mine. I will reread it a few more time to better prepare for this move. But I ask here, so that I may get a few ideas or tips.
Should I rebuild the 10.4 Server/ xserve G5 with the current servers IP and copy all the data, users and settings, then turn off the old then turn on the new? Or should I build it with a new IP, move data, test it, then changeip?
Or should I set it up as a secondary mail server and change the settings with our domain name registrar reflects the secondary mail server, then turn off the old one?
I know you're supposed to upgrade to 10.3.9 first, but 10.3.8 users do seem to import fine into 10.4.8 (in my tests). Anything really broken there?
I guess my concern are rooted in taking down a live working server, and establishing the safest way to bring up a new server which is fully functioning mail, web and dns. And I want chocolate ice cream too.
Thanks.

I know you're supposed to upgrade to 10.3.9 first, but
10.3.8 users do seem to import fine into 10.4.8 (in my
tests). Anything really broken there?
Yes. The OD schema changes from 10.3 to 10.4, and the upgrade
to 10.3.9 gets the OD schema into condition for migration to
10.4.x. That's the reason for that step.
Good details about the migration are given on
http://www.afp548.com
It's probably easier not to do the changeip flip, if you can
do that. Details at afp548.com

One thing that jumps out from your brief description of the problem is a bug in the persent iteration of Lion Server that occurs when the "Dedicate system resources to server services" box is checked (or, honestly, when it's unchecked too -- read on). This is located within Server.app. in the left pane, select your machine under the hardware section. The second tab, settings, contains this option. I'd try either ticking or unticking the box and then restarting and then trying to start those services again. Though the bug was initially reported as related to this similar problem (the one you describe) occurring when this box is checked, I've found that toggling between on to off, or off to on (depending on the current state) and then restarting, seems to help get things going again. Sometimes this has to be done twice. As well, until Apple issues a fix for these Server.app related problems, it's best, once you get your server configured, to keep from opening Server.app when possible. Just opening it seems to cause problems. One example of this is checking the mail quota box and entering a value. It seems to stick fine, but when Server.app is opened again, the box is unchecked once again. This one happens every time.

Import emails from Gmail / Google - Importar e-mails do Gmail / Google

I am gmail User and would like to import all mail to iCloud.com, because I want to start using the service from apple as my primary email. The issue is that I have many emails (70,000 +) and I can not import via a POP3 service. Could someone give me a hint?
Sou usuario do Gmail e gostaria de importar todos os emails para o iCloud.com, pois quero passar a usar o serviço da apple como meu email principal. A questão é que tenho muitos emails (+ 70 mil) e não tenho como importar atraves de um serviço POP3. Alguem poderia me dar uma sugestão?

You might want to rethink your strategy. All those emails, if put on icloud will count toward you free 5GB limit. Maybe start of moving some of those emails.
Using your computer, just drag-drop emails in the gmail box(es) into some mailbox in the icloud section. I'd do a few at a time, 70K+ files to move at once might cause problems.

Migrating from Linux to Mac OS X Server 10.5

Would appreciate any migration tips, especially those involving migrating user accounts and user mail over to the new server.
Any help would be appreciated.

You'll have to skip the authAuthority entries. One of them is for the password server, where Apple stores passwords, and the other obviously is for Kerberos. I think I read somewhere that you can actually use the userPassword: field if you put a plaintext password in there. I'd be interested to know if {crypt} or {md5} would work, like they do in regular OpenLDAP deployments.
Once you have the users imported into OpenDirectory, you can create the password server and Kerberos entries using the Server Admin tool, although this might require changing the password.
As for email, are you already using a recent version of Cyrus IMAP? If so, you just need to copy the files over (after importing users). If not, there are scripts floating around that can convert email from other systems to Cyrus.

Migrate from gMail to iCloud email : storage issues?

Hi
I'm considering dropping my existing but unwieldy gMail address, for a more concise [email protected] address. My concern is around storage space. It's my understanding that the standard iCloud account is just 5Gb - whereas the standard gMail account is limitless - correct? If so, surely my iCloud storage will in time, be consumed with large volumes of email. I'd then be forced to deal with that by 'spring cleaning' the iCloud server -and in the process, could lose something I later need.
Am I correct in assuming there's a 5Gb limit on iCloud acounts?
Matthew

5 GB's is the amount of the free service and you can purchase additional storage if needed.
I've had the same Apple mac.com address since 2000 and have less than 100 emails still on their servers. You can move files from iCloud to your computer to free up space.
