makeimapaccess rebuilds the contents of the /etc/courier/imapaccess.dat database from the contents of the
files in the /etc/courier/imapaccess directory. When the imapd script starts couriertcpd, the script
specifies the /etc/courier/imapaccess.dat file to control access to the Courier mail server's IMAP
daemon. The makeimapaccess script must be run before any changes in the /etc/courier/imapaccess directory
take effect.
The couriertcpd(8)[1] manual page describes the general format of access files.

The couriertcpd(8)[1] manual page describes the generic format of the access file. The access file
specifies what should be done with connections from defined IP address ranges. The basic choices are to
accept or reject the connection. Also, the generic format of the access file allows arbitrary environment
variables to be set based on the connection's remote IP address, however the IMAP server does not use any
special environment variables on its own.
