My users like to keep 500 to 1000 messages in their mailboxes and
average about 500K per message (we are a talent management company, so
there is lots of multimedia being exchanged).
So far I have been running whatever came stock with FC1, so I have
Postfix with WU IMAP running in that standard UNIX mailbox mode.
Can I keep Postifix and just change it to Cyrus IMAP style mailboxes and
install Cyrus IMAP? Or do I have to start from scratch?
Fortunately I have only 10 users, so I will have to deal with about 10K
in messages and about 150 sub folders.
Of course you can keep Postfix to run it in conjunction with
Cyrus-IMAPd. But be aware that migration from uw-imap is not that easy.
In any way, either after a fresh new install of FC2 with Cyrus-IMAPd or
after an upgrade, you will have to migrate the mbox format mails to the
format that Cyrus-IMAPd uses (a Maildir format). Cyrus-IMAPd comes with
a tool for that. You may alternatively go over a second IMAP server to
which you move the IMAP folder contents and after the main server was
migrated get back all the content.
Read the Cyrus-IMAPd documentation carefully. That daemon is much more
powerful than uw-imap and therefor needs more setup steps and
