Package: spampd Version: 2.30-23 Severity: important If spampd receives a SIGHUP it resets its options to the application's defaults ie. the options set in the script, not the options set in the service file or by the commandline flags.
The easiest way to demonstrate this is to start it as normal: # service spampd start Send SIGHUP to its pid: # kill -HUP `cat /var/run/spampd/spampd.pid` And then look in the mail.log for what has happened: spampd[3075]: 2016/12/29-00:24:04 Couldn't open pid file "/var/run/spampd.pid" [Permission denied].#012#012 at line 179 in file /usr/share/perl5/Net/Server.pm Dec 29 00:24:04 debian spampd[3075]: 2016/12/29-00:24:04 Server closing! It has tried to open the pid file in its default location of "/var/run/spampd.pid" instead of the location configured in the service file: PIDFile=/var/run/spampd/spampd.pid Although that location was used initially, it forgot it after the SIGHUP. The same thing happens if you start it from the commandline: # spampd --pid=/var/run/spampd/spampd.pid If you play with the permissions so that it can write the default pid file when HUP'd so it keeps running, other options reset as well such as the relay host/port options default to locahost:25 instead of localhost:10026 which in my setup creates an infinite mail loop (smtp server gives the mail to spampd which passes it back on port 25 so the smtp server gives it back to spampd and so on). I suspect what is happening is spampd calls GetOptions() which I think removes the commandline flags from @ARGS, and the documentation for the Net::Server module which spampd uses says not to alter the contents of @ARGS until ->run is called, so because of GetOptions(), when ->run is called @ARGS is empty so when Net::Server handles the HUP it reloads with no parameters set. -- System Information: Debian Release: 8.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_NZ.UTF-8, LC_CTYPE=en_NZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages spampd depends on: ii adduser 3.113+nmu3 ii dpkg 1.17.27 ii init-system-helpers 1.22 ii libnet-server-perl 2.008-1 ii lsb-base 4.1+Debian13+nmu1 pn perl:any <none> ii spamassassin 3.4.0-6 spampd recommends no packages. spampd suggests no packages. -- Configuration Files: /etc/spampd.conf [Errno 13] Permission denied: u'/etc/spampd.conf' -- no debconf information
