Description:

This package installs Courier mail server's integrated HTTP webmail
server. If you do not need the ability to access your mail using a web
browser, you do not need to install this package. Courier's webmail
server can only be used to download mail from maildir mailboxes. This
server does not support mailbox files.

This is the same server that's distributed separately under the name
of SqWebMail, however its configuration is customized for the Courier
mail server.
