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. -- System Information: Debian Release: 8.3 APT prefers stable APT policy: (500, 'stable') Architecture: armhf (armv7l) Kernel: Linux 4.1.6-249 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages greylistd depends on: ii adduser 3.113+nmu3 ii debconf [debconf-2.0] 1.5.56 pn python:any <none> Versions of packages greylistd recommends: ii exim4 4.84-8+deb8u2 greylistd suggests no packages. -- debconf information: greylistd/autoconfig_notdone: * greylistd/autoconfig_notdone_exim4: greylistd/restartexim: true
