SMTP error

[Per-fredrik Pollnow (EPK)]

Hi,

I was wondering, I get this error: 
warning: dropping connection, unable to read /etc/tcp.smtp.cdb: file does not exist

Ok, the file does not exist.. but were is it... do I have to install something more ? 
(I have installed ucspi-tcp-0.88 ).. 

and i'm using OpenBSD 2.9.. Thanx
