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.
Two things are true here: 1. If you don't have reverse DNS some servers will reject you - certainly still happens to our customers now and then 2. It's not well entrenched and therefore as Russell says, setting up your own server to reject on that basis is a complaint generator So, I would suggest keeping your own house in order, but not assuming that anyone else does is (as usual) the line of least resistance. cheers Brian
