Ubuntu server email transfer to new server

Hi please help,

I'm trying to decommission an old server but I need to transfer the mail stored to the new server.

The server is Ubuntu 10.04 LTS and its setup specification is exactly as shown in the Perfect Server Ubuntu 10.04 ISPConfig3 guide.

I have tried to copy /var/vmail to the new server which kind of works, in the INBOX there are some of the emails showing, but the others show "message unavailable."

Ironically every email in the trash folder is there and readable, typical!

However any custom folder created is missing. and again a large portion of the inbox mails are presumably missing as showing as unavailable.

I will be eternally grateful if someone can assist me with this one its driving me berserk!

Thanks in advance.

PS I can not forward each email one at a time it would take me months for each user :-(

Kind regards.

How about using imapsync ?

Yes this does indeed work, not the easiest way to migrate mailboxes as you have to do it one at a time which is still very impractical.

This link makes navigating the myriad of switches far easier

http://www.howtoforge.com/how-to-migrate-mailboxes-between-imap-servers-with-imapsync

I would still like to know if there's another way to replace all mailboxes & folders at once for all users rather than one at a time, such as copying /var/vmail across (this DOES NOT work correctly though)

I appreciate this could be quite easily scripted to copy everyones mailboxes but again that's still potentially a massive amount of work with a long list of users and passwords to process

Well I'm guessing that no one has any further suggestions for this one! oh well.

Thank you for pointing me in the right direction.

However, if anyone else can further expand on this for a more complete answer such as importing all mail accounts at once including folder creation and re-population I would be willing to award extra points

Kind regards.
