Hello! I am running latest version of toaster and had a client run into the qmail-dk signing issue last night - with only one email recipient. He tried multiple times to send the email - same thing.
"554 qmail-dk: Cannot sign message due to invalid message syntax. (#5.3.0)" Is it still best practice to unlink qmail-dk and use qmail-queue.orig? Is there a good way to use DKSIGNing? I found a reference to some scripts by a Kyle Wheeler. http://qmail.jms1.net/patches/domainkeys.shtml is DKSIGNing necessary or suggested? Is qmail-dk now reliable and something different caused the issue with this one recipient address? Thx!

Then on QMT, simply: # yum install caching-nameserver # service start named # chkconfig named on Then put nameserver 127.0.0.1 as the first record in your /etc/resolv.conf file. That's all you need to do. Your QMT host doesn't give a hoot about authoritative DNS. It'll get everything it needs from the recursor (aka caching-nameserver). -- -Eric 'shubes' On 04/26/2011 12:24 PM, Keith Smith wrote: What if I just wanted to by pass Bind for now and setup an MX record at my registrar? Would I just update my /etc/resolv.conf file with "nameserver IP-to-Registrar" the IP being the IP that the Domain resolves to? I want to do this to prove everything is working then add Bind so I do not have too may things going at once. Thanks Again for your help!

I am doing an install of Qmail Toaster on CentOS 5.6 using the documentation located at http://wiki.qmailtoaster.com/index.php/CentOS_5_QmailToaster_Install This is a test run to learn so I can do this in a production environment. The docs say I need a DNS server. I am using my registrar's DNS. Do I still need Bind or djbdns? Thank you for your help! -- There are 2 roles which are involved with DNS, an Authoritative server and a Recursor. An Authoritative server answers queries about specific domains which it 'owns', while a Recursor, aka caching nameserver, answers queries about any host in general. The two roles are typically implemented on different hosts, which is generally considered to be a good practice. While they can be implemented on a single host, doing so is more complicated, and has inherent security risks. Your registrar's DNS will serve as the Authoritative DNS server for your domain(s). The inbound MTA portion of QMT (smtp) uses DNS quite a bit, so it's a good idea to have a caching nameserver installed on the QMT host. This minimizes network DNS traffic, although DNS packets (UDP) really don't use much in the way of network resources to begin with. I usually install the caching-nameserver package (or pdns-recursor), add "nameserver 127.0.0.1" to the /etc/resolv.conf file, then forget about it. -- -Eric 'shubes' ---------------------------------------------------------------------------- ----- Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com <http://www.vickersconsulting.com>) Vickers Consulting Group offers Qmailtoaster support and installations.
