POP3 to CyrusIMAP migration howto ?

[Michael Menge]

Hi,

i know too different konzepts of migrating mailservers. They both have  
pros and cons.

1. split mbox, copy, reconstruct
    depending on how your POP-server stores the mails, you have to split
    each mailbox into single files for every e-mail. Then you copy the files
    to the cyrus folder and run reconstruct.
    But you will loose the seen status and you may have to change the files
    depending on the fileformat of the original inbox.

2. use POP/IMAP-Protokoll to copy the e-mails from one server to another.
    I have only tested this for Imap-Imap transfers, but mailutil (part of the
    UW-Imap) can handle different types of servers.
    You must know the passwords, or be able to gain access to the
    POP/IMAP account
