IMAPcopy is a small utility that will help you migrate from one IMAP e-mail message store to a another one.  I generally try to use this utility from the command line of one of the servers involved in the transfer in order to minimize traffic and time.  You can copy many users at once, if you wish.

The following are just my notes on this subject.

tar -xzvf imapcopy.tar.gz
cd imapcopy

Edit the Config File for Each Job

vi  ImapCopy.cfg

Make it look like:

#CreateEmptyFolders

skipfolder INBOX.Trash
skipfolder INBOX.Sent
skipfolder "INBOX.Deleted Items"
skipfolder "INBOX.Sent Items"
skipfolder "INBOX.Junk E-Mail"

skipfolder Trash
skipfolder Sent
skipfolder "Sent Items"
skipfolder "Junk E-Mail"
skipfolder "Deleted Items"

 

DenyFlags "\Recent"

 

#          SrcUser       SrcPasswd            DestUser        DestPasswd
#Copy   "bar"           "barsrcpw"           "bar"               "bardestpw"
#Copy   "bar"           "barsrcpw"           "bar"               "bardestpw"
Copy     "username"  "password"          "newuser"        "newpassword" 

Now verify that all users and passwords are correct:

./imapcopy -t

Then transfer the messages if all is well:

./imapcopy
