hosts.allow error

I'm running sendmail on a RH9 PC at the moment, soon to change that one to
fedora C1 or C2 also. My question is about a message I get from sendmail. I
copied it from the email:
 --------------------- sendmail Begin ------------------------
Relaying denied:
    From [211.158.122.149] to a@xxxxx: 1 Times(s)
    From md-wmnsmd-cuda1-a4a-a-43.chvlva.adelphia.net [xx.xx.xxx.xx] to
xxxx@xxxxxxx: 2 Times(s)

**Unmatched Entries**
   /etc/hosts.allow, line 7: missing ":" separator: 144 Time(s)
   /etc/hosts.allow, line 6: missing ":" separator: 144 Time(s)

What does it mean when it say's the ":" separator is missing?

Thanks,

Scott....
