Description:

This package installs Courier mail server's integrated IMAP server. If
you do not need the ability to download your mail using an IMAP mail
client, you do not need to install this package. Courier's IMAP server
can only be used to download mail from maildir mailboxes. This server
does not support mailbox files.

This package requires that Courier must be already installed, this is
NOT the standalone version of the Courier-IMAP server, and you cannot
install both this package, and the standalone version of Courier-IMAP.
If you have the standalone version of the Courier-IMAP server already
installed, installing this package will automatically remove the
standalone version.
