Changes

Postfix is capable of performing the function of an LDA, but its LDA capabilities are limited, thus postfix is generally not used for that purpose. Currently, the most popular LDA is ''LMTP'', but we will be installing, configuring, and using an LDA called '''Dovecot''' since it is also popular and we will later be setting up Dovecot as an '''IMAP''' server. Using both Postfix and Dovecot will actually increase the performance of our IMAP server.

#Dovecot is not installed when you installed your Virtual machines in previous labs.
