Hi, I am having some problems with imapsync. After reading the helpful article written by Falko Timmer on How To Migrate Mailboxes Between IMAP Servers With imapsync, I tried to do it myself. When I run imapsync on Ubuntu Server 10.04 to sync between two IMAP servers (one server runs on hMailServer and the other runs on Dovecot IMAP), I received some duplicates mails. Not only that, it does not completely sync the mails because I can find the mails on one server but did not see them on the other server, especially, the mails are most recent ones. The command I used was $sudo imapsync --host1 example.com -- user1 email@example.com --password1 xxxxxxx --noauthmd5 --host2 localhost --user2 jwilliams -password2 xxxxxxx --noauthmd5 Any help would be greatly appreciated.
