Package: bind9-host Version: 1:9.2.4-1 Severity: normal
Hi LaMont! I cannot actually tell if it's a bug or not, but it causes quite a problem with postfix: ----------------- snip ---------------- # host -v -t mx p-net.de ns.vnet.de Trying "p-net.de" Using domain server: Name: ns.vnet.de Address: 195.4.192.5#53 Aliases: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 33635 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;p-net.de. IN MX ;; AUTHORITY SECTION: p-net.de. 86400 IN SOA ns.vnet.de. support.iworld.de. 2006010202 28800 7200 604800 86400 Received 85 bytes from 195.4.192.5#53 in 40 ms ------------------- snap ----------------------- As you can see, the server is authoritative and returns no result for the MX lookup. The Postfix on that box makes of that: Jan 25 10:21:05 ns3 postfix/smtp[7249]: 2EFFE19402E: to=<[EMAIL PROTECTED]>, relay=none, delay=0, status=bounced (mail for p-net.de loops back to myself) If I do the VERY SAME on my Debian/testing box, I get: -------------- snip --------------- # host -v -t mx p-net.de ns.vnet.de Server: ns.vnet.de Address: 195.4.192.5 Query about p-net.de for record types MX Trying p-net.de ... Query failed, 0 answers, authoritative status: no error Authority information: p-net.de 86400 IN SOA ns.vnet.de support.iworld.de ( 2006010202 ;serial (version) 28800 ;refresh period (8 hours) 7200 ;retry interval (2 hours) 604800 ;expire time (1 week) 86400 ;default ttl (1 day) ) p-net.de has no MX record at ns.vnet.de (Authoritative answer) ------------------------ snap ----------------- So, it's a different result from the DNS. And postfix reacts accordingly -- as expected (by me, that is): Jan 25 10:22:26 mail postfix/smtp[20375]: 041692206A3: to=<[EMAIL PROTECTED]>, relay=none, delay=1, delays=0.96/0.07/0/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=p-net.de type=A: Host found but no data record of requested type) So, is this a bug in the resolver, libc6 or what is it? -- System Information: Debian Release: 3.1 Architecture: i386 (i686) Kernel: Linux 2.6.15.1 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages bind9-host depends on: ii libc6 2.3.2.ds1-22 GNU C Library: Shared libraries an ii libdns16 1:9.2.4-1 DNS Shared Library used by BIND ii libisc7 1:9.2.4-1 ISC Shared Library used by BIND ii libssl0.9.7 0.9.7e-3sarge1 SSL shared libraries -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
