We will begin by using the existing Postfix service You may ask yourself, ''"why not install on your VM3 VM2 machine, then add an Local Delivery Agent (since we used the VM2 machine in the previous lab?"''. The reason for this approach is to separate the two types of services: '''LDAIMAP''') by installing the vs '''dovecot-ldaPOP3''' package, configure it, and test ti to make sure that is is working correctly.

We will begin by using the existing '''Postfix''' service on your '''VM3''' machine, then add an Local Delivery Agent ('''LDA''') by installing the '''dovecot-lda''' package, configure it, and test ti to make sure that is is working correctly. Finally, we will set up an '''IMAP''' server (Dovecot) so you can read your email from an MUA such as ''Thunderbird '' or a ''Webmail '' (we will set up a webmail application in a later lab).
