Package: greylistd
Version: 0.8.8.5
Severity: normal

Dear Maintainer,

The header in /var/etc/greylistd/whitelist-hosts specifies:
### Most MTAs support at least the following:
[...]
###  - Between one and three octets, indicating an IPv4 network:  192.168.0

But Exim does not, and the rest of the comment suggest this
would. Combined with the fact that Exim is extremely quiet
about the error and ends up ignoring the entire file, this
makes it very easy to end up with a system that ignores the
white list...

I suggest replacing the line:
###  - Between one and three octets, indicating an IPv4 network:  192.168.0

with:
###  - A sub-network specification: 192.168.0.0/24


Cheers,
Y.
