These days it is also essential that mail servers have a suitable reverse DNS (rDNS) entry as well.
15 years ago it was essential. Nowadays no-one cares.
If you configure a mail server to reject servers without reverse DNS then you will have all the users immediately complain.
If you install a server on a static IP address assigned by an ISP then you probably won't be able to install reverse DNS.
My mail server hasn't had reverse DNS for years, it hasn't caused me problems.
My experience is the exact opposite. I ran my mail server for years and never had any rDNS, then all of a sudden in a short period of time, lots of servers refused to work properly until I got my rDNS setup -- then no further problems. I do use a static IP from my ISP. So, my experience is, that you MUST absolutely have rDNS to operate a mail server and not risk other mail servers "thinking" this is not a "real" mail server, so we can ignore them.
