Hello,

I am in the process of migrating my clients from a flavor of Linux (not sure what it is) on Network Solutions servers to a Postfix server.  I need to migrate mail, contacts and calendars.  Any ideas?

Thanks for your help,

Don

Hello,

On the existing server (Network Solutions) I do not have SSH access, just standard EU web access. Outlook, etc.

Have a great day,

Don

create account by exporting the details from CSV and import via webmin over linux postfix box ... then to sync the data .. the simplest way i suggest is sync the accounts with IMAPSYNC

No, I do not know what they are using.  It just says Network Solutions WebMail.

OK... IMAPSYNC is best option in this case but i am afraid you might need to create mail accounts manually incase you are unable to find anything from them.

Sandeep,

I do not see anywhere to export to CSV.  Beyond that, you are talking over my head.

The existing accounts are POP, not IMAP.

:D

1. Configure those accounts on any email client via POP to fetch the mails. Convert them into .pst file.

2. Re-create the account in Postfix and create mailboxes then either you can sync them with all of your old data else you can simply add .pst to new mailbox and can start using your mails from postfix.

Hope this helps... Actually i know the pain behind migrating netsol to somewhere else....

I think you are saying use Outlook/PST to retrieve data from current account, then connect to the new Postfix server and continue using the same PST file.  This will not work.  I need to get the mail moved to Postfix in some way because the EU is using webmail interface and not Outlook or any other 3rd party app.

then the only way i have with me is IMAPSYNC.. open a support ticket with netsol and asked to enable IMAP in case not enabled...

Once IMAP is enabled you can migrate data from netsol to postfix directly (no ssh, no login needed) What just you need mail account at both ends to do this activity.

Actually, NSI does have IMAP access.  Will this copy all mail in all folders, contacts and calendar?

I know for fact IMAP is setup.  I just tested it.  I did not get a clear answer about all of the mail.  Will all of the folders be copied/migrated over?

Depending on how many users there are, a painless solution would be to set up the postfix server from scratch and create the mailboxes for the users.

You will the connect them to the webmail using IMAP / POP to sync or download the current e-mail.

I have not been able to import contacts and calendars to a postfix server, however you can try and export those from the webmail if there is an option.

I am using Ubuntu Server v13.04.

At this point, I am just migrating 3 accounts so starting from scratch would not be practical.

I think GEMCC means that it's not in a repository that can easily be added/installed with apt-get or aptitude.


@GEMCC
If it's available for linux, it's available for any linux, even ubuntu.  You may just have to download the source yourself, manually compile it, and install it.  It just won't be automatically updated when you use your distro's standard installation and update channel.  You will have to keep track of the patches and updates and manually download the next version and compile it again.

OK, this is what I did:

Using a POP connection, I downloaded the mail to a PST file.  Then I connected to the new server via IMAP and copied the mail over.

It would be better to give experts some points rather than deleting the question, what you did was suggested.

By who?  I looked and I could not find one that said this.  I do not care about points at all.  They do not mean anything to me.  What I care about is what is the correct answer so when someone else does a search, they know exactly what was done.

Tell me who gave me the exact same answer and I will give them the credit deserved.

Thank you

Actually ID: 39838037 is not entirely accurate as to what I did.  It does not mention connecting to the new server using IMAP and then copying the messages over.

Again, I do not care about the points, what I care about is the accuracy of the answer and having an accurate knowledge base.

Do whatever you need to do.

This site is not accurate of what the issues are because of "points".  People are to worried about "points".  I do not care about "points".  I care about accuracy of answers to problems.  I waste way too much time trying to figure out what the REAL answer to a problem is all because this site and members are concerned about points.

Seriously considering cancelling my account.

That was half the resolution, that is what you are missing.

Please do what you need to do.  I am not going to respond to this anymore.
