We You will begin by modifying the existing '''Postfix''' servers to make mail they send come from your domain, (instead of each machine). Then we you will add a record to your DNS server to allow mail to be sent to the domain itself, instead of the individual machines. Next we will add a Local Delivery Agent ('''LDA''') to your '''vm3''' by installing '''dovecot-lda''', 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'' application (we such as Roundcube). You will set up a webmail application later in a later labLab 8).
