    Lightbulb Guide to Migrate from Sendmail/Pop3/IMAP to Ubuntu Zimbra

    I've just followed the Ubuntu installation guide and then proceeded to migrate my mail from Redhat Sendmail/Pop3/IMAP to Ubuntu 6.06 Server.

    There is info in these forums how to do it but scattered about.

    Here's a quick migration guide:

    You'll need to have IMAP running on your old server. In my case it was present but disabled.

    On zimbra server, as root

    1) apt-get install build-essential

    2) apt-get install make

    3) apt-get install libio-socket-ssl-perl

    4) Get Mail-IMAPClient-2.2.9 from

    5) Gunzip & untar, and follow instructions in Mail-IMAP/INSTALL to install

    6) Download TermReadKey-2.30 from

    7) Gunzip & untar TermReadKey and do same as Mail-IMAP to install (perl Makefile.PL, make, make test, make install)

    8) Get imapsync from

    9) Gunzip & untar imapsync

    10) in imapsync dir, use the following command:

    ./imapsync --nosyncacls --syncinternaldates --host1 old_mail_server --user1 old_server_username --password1 oldserverpwd --host2 new_zimbra_server --user2 new_zimbra_username --password2 new_zimbra_pwd --authmech1 LOGIN --authmech2 LOGIN

    You can add --folder INBOX to only sync the inbox folder. And there are other options too, ./imapsync to display the help

    Yes you need to run imapsync for each user, but this can be scripted.
