Summary : Server daemons for IMAP and POP network mail protocols.
Description :
The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access
protocols. The POP protocol uses a "post office" machine to collect
mail for users and allows users to download their mail to their local
machine for reading. The IMAP protocol allows a user to read mail on a
remote machine without downloading it to their local machine.
Install the imap package if you need a server to support the IMAP or
the POP mail access protocols.
