The other day I was asked to install a completely new email server and transfer all the email accounts from the old mail server to the new one. I noticed that since the new mail server was using a different mail INBOX format I had to do some research and found this really good tool to do exactly what I needed called: imapsync
Installing the tool:
This tool programmed in Perl and is not free. It can be bought at //imapsync.lamiral.info/.
Note: It does a great job and it’s really worth its price when you think of the time and hassle saved by using it.
Using the tool:
Example 1: Copying all the mails in folder INBOX from jim account on localhost to another server with the same credentials:
– First we do a dry-run to see what will be transferred when I run it normally:
imapsync --dry \
--host1 localhost --user1 jim --password1 'secret1' --folder INBOX --tls2 \
--host2 mail.myserver2.com --user2 jim --password2 'secret1' --nofoldersizes --nofoldersizesatend
Example 2: Copying all the mails and folders(no dry-run) from account firstname.lastname@example.org on localhost to a new account on another server with different credentials:
--host1 localhost --user1 email@example.com --password1 secret1 \
--host2 mail.myserver2.com --user2 firstname.lastname@example.org --password2 secret2
