it seems to be complaining that lists.digium.com does not match

so either the reverse dns should to be fixed or the hostname used by the

Or... you need to tune SpamAssassin. IIRC (but I could be wrong), DNS
servers should have a PTR record, not necessarily reverse matching forward.
In general that is correct.
But the etiquette for SMTP is the HELO is done with a reverse friendly
name.
This 'assists' in detection of spoofed dns spamming.
EX:
64.4.32.7 connects to mail.pdinc.us and says:
HELO mail.ibm.com
mail.pdinc.us should mark the message as:
received from mail.ibm.com (hotmail.com [64.4.32.7])
and the user should then know that there is something wrong
hotmail.com != ibm.com
So no, it is not SpamAssassin which needs tuning in this case,
lists.digium.com should say
HELO digium-69-16-138-164.phx1.puregig.net
instead.
