Package: postfix Version: 3.4.5-1+b1 Severity: normal With the default debian configuration postfix runs chrooted and the systemd unit, through the pre-start script /usr/lib/postfix/configure-instance.sh copies the environment (including /etc/resolv.conf) to the chroot.
However, on a new laptop with a fast boot (and fast disk) postfix may start before the DNS received by DHCP is configured in resolv.conf, thus postfix has no DNS. -- System Information: Debian Release: bullseye/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.2.0-2-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE= (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages postfix depends on: ii adduser 3.118 ii cpio 2.12+dfsg-9+b1 ii debconf [debconf-2.0] 1.5.73 ii dpkg 1.19.7 ii e2fsprogs 1.45.3-4 ii libc6 2.28-10 ii libdb5.3 5.3.28+dfsg1-0.6 ii libicu63 63.2-2 ii libsasl2-2 2.1.27+dfsg-1 ii libssl1.1 1.1.1c-1 ii lsb-base 11.1.0 ii netbase 5.6 ii ssl-cert 1.0.39 Versions of packages postfix recommends: ii python3 3.7.3-1 Versions of packages postfix suggests: ii bsd-mailx [mail-reader] 8.1.2-0.20180807cvs-1+b1 ii dovecot-core [dovecot-common] 1:2.3.4.1-5 ii emacs-lucid [mail-reader] 1:26.1+1-3.3 ii kmail [mail-reader] 4:18.08.3-1 ii libsasl2-modules 2.1.27+dfsg-1 ii mutt [mail-reader] 1.10.1-2.1+b1 pn postfix-cdb <none> pn postfix-doc <none> pn postfix-ldap <none> pn postfix-lmdb <none> pn postfix-mysql <none> pn postfix-pcre <none> pn postfix-pgsql <none> pn postfix-sqlite <none> pn procmail <none> ii resolvconf 1.79 ii s-nail [mail-reader] 14.9.13-2 pn ufw <none> -- Configuration Files: /etc/postfix/post-install [Errno 2] No such file or directory: '/etc/postfix/post-install' /etc/postfix/postfix-files [Errno 2] No such file or directory: '/etc/postfix/postfix-files' /etc/postfix/postfix-script [Errno 2] No such file or directory: '/etc/postfix/postfix-script' -- debconf information: postfix/main_cf_conversion_warning: true postfix/dynamicmaps_conversion_warning: postfix/mydomain_warning: * postfix/mailbox_limit: 0 * postfix/root_address: postfix/rfc1035_violation: false * postfix/relayhost: mail.rail.eu.org postfix/retry_upgrade_warning: postfix/sqlite_warning: postfix/newaliases: false * postfix/protocols: all postfix/tlsmgr_upgrade_warning: * postfix/main_mailer_type: Satellite system postfix/kernel_version_warning: postfix/lmtp_retired_warning: true * postfix/chattr: false postfix/compat_conversion_warning: true * postfix/mynetworks: 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 postfix/procmail: false * postfix/destinations: postfix/not_configured: postfix/bad_recipient_delimiter: * postfix/mailname: maine-ocean.rail.eu.org postfix/relay_restrictions_warning: * postfix/recipient_delim: +
