IIRC, that kind of behavior will only cause you problems. There are
a large number of MTAs where their identity does not necessarily map
using reverse DNS (such as if smtp.example.com has multiple A records
which reverse map to host1.example.com, host2.example.com, etc). It
may also break where the MTA is being NAT'd, which is becoming more
common with many small companies having a single point of presence with
a single IP, often over cable modem or DSL.
Speaking of spam, is this mailing list protected by RBL? There's been a
fair amount of crap, recently.
