Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.
Seeing as it does not work right now, I don't know where the servers are listed on his system. Clearly there must be some configuration issue. But at the same time, IMHO it is the best solution to ensure there is a properly configured local DNS server. Such a local DNS server has a config where you can list forwarding DNS servers and that is where his name servers should be configured. Imagine resolv.conf lists the two outside DNS servers directly. Let's assume that the first entry (will be queried first) is down. Although the system tries to send 50 individual mails to some...@googlemail.com, the mail server will experience a timeout for the first name server and only then query the secondary server. All that happens 50 times(!) Now, if you have a working caching DNS server, as soon as the first timeout happened and the secondary DNS server was queried, the local server has the DNS entry stored and the remaining 49 messages do not encounter any timeout at all.

Hi, So what/where are the two dns servers Marek says he is using? On 14/02/2011 7:02 PM, Martin Waschbüsch wrote: That is not correct! If localhost runs a caching DNS server, it will fetch DNS information from forwarding DNS servers, which can be the ISP's, Google's, whatever. The whole point of having a local caching DNS server is that it not only takes care of using all DNS servers it knows about to fetch data, but also to store that data and prevent DNS-lookup-heavy applications (like E-Mail servers) to generate lots of additional traffic and overhead. So, if Marek runs a local DNS server and still gets problems, then we need to look at that config. If not, he really should install a caching DNS server (named, djbdns, etc.) In any case, resolv.conf is just fine only pointing to the local server.

Sounds like you have lookups configured incorrectly on the system. When a message is sent, a MX lookup in DNS takes place during the smtp process. It will fail during this transaction, since the system cannot lookup remote MX records to determine where to send mail to. Double check your lookup configuration on this host. I thought I read somewhere later in the thread that you have 127.0.0.1 listed in resolv.conf - this would lead me to assume you have a caching DNS server setup on this machine as well. If this is the case, for Bind, check your named.conf file to ensure your forwarders include more than just the one DNS server that goes down.
Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.
That is not correct! If localhost runs a caching DNS server, it will fetch DNS information from forwarding DNS servers, which can be the ISP's, Google's, whatever. The whole point of having a local caching DNS server is that it not only takes care of using all DNS servers it knows about to fetch data, but also to store that data and prevent DNS-lookup-heavy applications (like E-Mail servers) to generate lots of additional traffic and overhead. So, if Marek runs a local DNS server and still gets problems, then we need to look at that config. If not, he really should install a caching DNS server (named, djbdns, etc.) In any case, resolv.conf is just fine only pointing to the local server.

Ok. I try put IP number of second DNS into resolv.conf But its look like second DNS will newer be visible if i forgot put ip number in resolv.conf.

Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.
1. Perhaps make the local dns the primary (first) listed in /etc/resolv.conf 2. Have nagios or another monitoring script notify you and / or restart the secondary dns server when it fails 3. Definitely find out why the second dns server keeps failing and fix it Regards, Randy On 2/13/2011 2:03 PM, d...@demod.pl wrote: Thanks for fast reply.

Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.
What you could try is this: Have a local caching DNS server and that takes care of resolving to as many 'real' DNS servers as you like. Doing so means that your DNS server (local) is ALWAYS on (unless the daemon dies) and this problem won't occur again.
