Sorry, there is too much spam coming from customers of your ISP and your ISP is not doing a good job of stopping it.  If you are a legitimate mail domain you must have a correctly configured reverse DNS.
That's a 'catch 22'.

Matt's MTA seems to be set to block 'allocated portable' source IP's
with no DNS record of their own, i.e. those running an MTA on their
own PC with dial-up, cable, or ADSL.

Downside is that the 'upstream ISP', in many cases,
has an *abysmal* record and is often in one or several
RBL's - and should be.

Matt seems to use 'strict' rDNS lookup.  Mainline MTA authors,
(Hazel, Varshavchick, Venema, et al) are more sanguine,
'coz rDNS is quite often non-exisistent or incorrectly
configured (most virtual-hosting, for example).

Most will assign negative spam score points for lack of
rDNS, but not block outright.  If nothing else is negative
your message goes through.  Not so on backplane.com

As rDNS can also be utilized by spammers to target their
attack to specific demographics, some folks don't use it.

Horses for courses.....
