chmod +x imapsync

3. Perform a test:
./imapsync –testslive

4. Install IMAPsync on the system:
cp imapsync /usr/bin/

5. Synchronize mail between servers:

imapsync \
--host1 MailServer1 --user1 User1 --password1 Password1 \
--host2 MailServer2 --user2 User2 --password2 Password2

or

imapsync --host1 MailServer1 --user1 User1  --password1 Password1  --host2 MailServer2  --user2 User2 --password2 Password2

Change MailServer1 and MailServer2 to your E-Mail servers, User1 and User2 to your username and Password1 and Password2 to your password!
