Package: postfix-policyd-spf-python Version: 2.0.1-1 Severity: important Hello,
Package: postfix-policyd-spf-python Version: 2.0.1-1 postfix-policyd-spf-python fails to properly failover to a secondary nameserver in case one of the declared nameservers in /etc/resolv.conf is not responding. All incoming email is rejected with: defer_if_permit 4.7.24 Message deferred due to: SPF Temporary Error: DNS Timeout. Please see http://www.openspf.net/Why?s=[snipped] related to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=718547 but python- dns is not installed, so I'm thinking that the underlying problem is actually in postfix-policyd-spf-python. No difference with python-dns installed. The problem goes away if I manually remove the non-responding nameserver from /etc/resolv.conf Thank you, Demetris Demetriou -- System Information: Debian Release: 9.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-8-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages postfix-policyd-spf-python depends on: ii adduser 3.115 pn postfix <none> ii python3 3.5.3-1 pn python3-authres <none> pn python3-spf <none> postfix-policyd-spf-python recommends no packages. postfix-policyd-spf-python suggests no packages.
