One of the reason I haven't put this in production yet is that some
users have dkim enabled and this will replace the qmail-remote perl file
with a qmail-remote binary. I guess I have to figure out a way around it
maybe some checking during install along these lines: if
qmail-remote.orig exists back it up (qmail-remote.orig.bak) and replace
it with the new binary.

Seems like this should show up when I do a yum update if I have the
qmt.repo enabled. Or maybe it's still in testing? Which I don't have
enabled by default.

Hi Peter,
This is not a Big DNS failure. It's a problem with CNAME lookup, and
qmailtoaster is patched with the Big DNS patch.
Dan Bernstein recommended <https://lists.gt.net/qmail/users/138190>
the removal of the CNAME lookup portion of the code (patch below),
which I did, a function in dns object module which is called by
qmail-remote. There are new binaries with this patch at the following
locations for respective CentOS version:
CentOS 7:
ftp://ftp.qmailtoaster.org/pub/repo/qmt/CentOS/7/development/x86_64/qmail-1.03-2.2.qt.el7.x86_64.rpm
CentOS 6:
ftp://ftp.qmailtoaster.org/pub/repo/qmt/CentOS/6/development/x86_64/qmail-1.03-1.1.qt.el6.x86_64.rpm
CentOS 5:
ftp://ftp.qmailtoaster.org/pub/repo/qmt/CentOS/5/development/i386/qmail-toaster-1.03-1.3.23.i386.rpm

I am getting this error when sending to the tyks.fi domain:

I've been searching for this error and found the following:
1) known error for qmail + bind combination
2) fix is to either patch with qmailtoaster-big-dns.patch or use other
recursor than bind
Before I can proceed with 2) I have some questions though:
* Why is the patch not installed by default in the toaster? I can see
Shubert had it:
https://github.com/QMailToaster/qmail/blob/master/qmailtoaster-big-dns.patch
* As I understood it, the problem is a response too big that BIND
cannot handle. I am a bit confused here, as the tyks.fi lookup does
not return a big response and it does not have any CNAME records in
it. Could this error be caused by something else?
* If I would to change resolveer and not to patch, can I both run a
BIND server and have a different resolver at the same time on the same
server?
Best,
Peter
