That's because, as you stated in a previous message, you have a deny list containing that hostname. Exim looks up the hostname when it gets a connection to see if the IP the connection is from that host. That hostname doesn't resolve:
$ dig phpbbspprt840.gmail.com
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.5 <<>> phpbbspprt840.gmail.com

So each connection will have that message.
