Dear all,
I have a mail server which only running Postfix and OpenWebmail. At present, the system is operating normally. We can send and receive mail. Our system have approximately about 80 users. The users have stored their mail on server and access mail via Openwebmail. We are compiling Cyrus IMAP additionally to access mail via IMAP. However, we only have authentication via IMAP but can't get mail via IMAP. Do you have any ways to rebuild the structure of mailbox to access via IMAP (The users can access via IMAP to get old mail )?

Thanks,

personally i would suggest looking at dovecot, which slots into postfix's Maildir format by default. courier and cyrus are generally more involved, and if you're just after an IMAP connection, migth put you off!

Dear acid_kewpie,
We are using mailbox format, not maildir format. So, does Dovecot support for mailbox format purely?

Best regards,

Yes i think it does too AFAIR. if the mail location ends in a / then it's a directory by implication...
