Server step 4

Time to move old mail to the new server

root@proliant:# aptitude install imapsync

root@proliant:# imapsync --host1 mail --user1 user --passfile1 secret1 --host2 localhost --user2 user --passfile2 secret1 --delete2 --noauthmd5

And don't forget to create password file secret1

That should take a while
