Package: exim4 Version: 4.72-6+squeeze2 Severity: normal We have Exim configured with 2 smarthosts, for redundancy:
dc_eximconfig_configtype='smarthost' [...] dc_smarthost='mailhost.uk.bluearc.com:mailhost.us.bluearc.com' [...] This morning, unfortunately, the second name in that list stopped resolving. (It is CNAMEd to something that currently returns NXDOMAIN.) The failure was noted in mainlog like this: 2012-02-06 09:41:38 1RuL4s-0001wA-0A == t...@bluearc.com R=smarthost defer (-36): host lookup for mailhost.us.bluearc.com did not complete (DNS timeout?) Surprisingly, Exim seems not to have tried using the other, still working, smarthost at all (the first listed). No messages were delivered until I removed the faulty smarthost from the configuration and flushed the queue. It is clearly undesirable that failure of a backup smarthost should prevent Exim delivering via a preferred smarthost that has not failed. -- Package-specific info: Exim version 4.72 #1 built 12-May-2011 18:50:41 Copyright (c) University of Cambridge, 1995 - 2007 Berkeley DB: Berkeley DB 4.8.30: (April 9, 2010) Support for: crypteq iconv() IPv6 GnuTLS move_frozen_messages DKIM Lookups: lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmnz dnsdb dsearch nis nis0 passwd Authenticators: cram_md5 plaintext Routers: accept dnslookup ipliteral manualroute queryprogram redirect Transports: appendfile/maildir/mailstore autoreply lmtp pipe smtp Fixed never_users: 0 Size of off_t: 8 GnuTLS compile-time version: 2.8.6 GnuTLS runtime version: 2.8.6 Configuration file is /var/lib/exim4/config.autogenerated -- System Information: Debian Release: 6.0.3 APT prefers stable APT policy: (990, 'stable'), (500, 'oldstable'), (500, 'stable'), (50, 'unstable'), (50, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/12 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages exim4 depends on: ii debconf [debconf-2.0] 1.5.36.1 Debian configuration management sy ii exim4-base 4.72-6+squeeze2 support files for all Exim MTA (v4 ii exim4-daemon-light 4.72-6+squeeze2 lightweight Exim MTA (v4) daemon exim4 recommends no packages. exim4 suggests no packages. -- debconf information: exim4/drec: -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
