Package: postfix Version: 3.4.14-0+deb10u1 Severity: grave Justification: causes non-serious data loss
My server is blacklisted by Spamhaus, which says: Please correct your HELO localhost.localdomain [...] at https://www.spamhaus.org/query/ip/2001:4b99:1:3:216:3eff:fe20:ac98 I don't know why it did that, and I don't know how to reproduce it (I've just done a test, and it used joooj.vinc17.net as expected). This might have been a temporary error under some condition, but this is not acceptable. Note: the FQDN of the machine is normally obtained via /etc/hosts, which is ------------------------------------------------------------ 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters 155.133.131.76 joooj.vinc17.net joooj ------------------------------------------------------------ I'm wondering: perhaps a temporary IPv4 failure leads to the issue, and postfix has a hardcode localhost.localdomain in case of failure? -- System Information: Debian Release: 10.10 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-debug'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-17-amd64 (SMP w/1 CPU core) Locale: LANG=POSIX, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE=POSIX (charmap=UTF-8) Shell: /bin/sh linked to /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 ii debconf [debconf-2.0] 1.5.71 ii dpkg 1.19.7 ii e2fsprogs 1.44.5-1+deb10u3 ii libc6 2.28-10 ii libdb5.3 5.3.28+dfsg1-0.5 ii libicu63 63.1-6+deb10u1 ii libsasl2-2 2.1.27+dfsg-1+deb10u1 ii libssl1.1 1.1.1d-0+deb10u6 ii lsb-base 10.2019051400 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 ii emacs-nox [mail-reader] 1:26.1+1-3.2+deb10u2 ii libsasl2-modules 2.1.27+dfsg-1+deb10u1 ii mailutils [mail-reader] 1:3.5-4 ii mutt [mail-reader] 1.10.1-2.1+deb10u5 pn postfix-cdb <none> ii postfix-doc 3.4.14-0+deb10u1 pn postfix-ldap <none> pn postfix-lmdb <none> pn postfix-mysql <none> ii postfix-pcre 3.4.14-0+deb10u1 pn postfix-pgsql <none> ii postfix-sqlite 3.4.14-0+deb10u1 ii procmail 3.22-26 pn resolvconf <none> ii sasl2-bin 2.1.27+dfsg-1+deb10u1 pn ufw <none> -- debconf information: postfix/tlsmgr_upgrade_warning: postfix/sqlite_warning: postfix/relayhost: * postfix/destinations: joooj.vinc17.net, vinc17.net, joooj, localhost.localdomain, localhost postfix/lmtp_retired_warning: true * postfix/procmail: true postfix/relay_restrictions_warning: * postfix/mailbox_limit: 1073741824 * postfix/root_address: * postfix/chattr: true * postfix/mynetworks: 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 postfix/mydomain_warning: * postfix/mailname: vinc17.net postfix/compat_conversion_warning: true postfix/not_configured: * postfix/recipient_delim: - * postfix/protocols: all postfix/kernel_version_warning: postfix/newaliases: false postfix/bad_recipient_delimiter: postfix/dynamicmaps_conversion_warning: postfix/rfc1035_violation: false * postfix/main_mailer_type: Internet Site postfix/retry_upgrade_warning: postfix/main_cf_conversion_warning: true -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
