You may ask yourself, ''"why not install on VM2 machine, since we used the VM2 machine in the previous lab?"''. The reason for this approach is to separate the two types of services: '''IMAP''' vs '''POP3'''.

We The reason for this (described in the previous lab) was that you will be able to send email out of your network, and receive email from within your network, but you will begin by using the existing '''Postfix<u>not</u>''' service on receive email from outside of your network due to the following reasons:* Individuals outside of your domain will never find the MX records because there are no '''VM3.org''' machine, then add an Local Delivery Agent servers pointing to your DNS server (i.e. you haven'''LDA'''t paid for it) by installing .* Even if the individuals could read your MX records, your local network is using IP addresses on a '''dovecot-ldaprivate subnet''' package, configure which is not routeable on the Internet, so it, and test ti to make sure that is is working correctlycannot be reached from outside of your system.

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 on VM3, configure it, and test it to make sure that is is working correctly. Finally, we will set up an '''IMAP''' server (Dovecot) on VM3, 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).
