imsimport migrates the specified /var/mail/folder for the specified user to the Sun Java System Messaging Server message store. If the destination folder is not specified, imsimport calls the destination folder by the same name as the source folder. In the following example, the command migrates the default /var/mail INBOX for the user smith, to the INBOX.
imsimport -u smith -s /var/mail/smith -d INBOX |
Similarly, if you are trying to move a folder called test from /home/smith/folders/ to the Sun Java System Messaging Server message store, use the following command:
imsimport -u smith -s /home/smith/folders/test -d test |
If a destination folder called test already exists in the Sun Java System Messaging Server message store, imsimport appends the messages to the existing folder in the mailbox.
