Hi Peter:
There is a new version of the qmail toaster that has this patch
installed. Please reach out to the QMT maintainer Eric Broch for more
information.
There's a long story on this issue going back to Dan Bernstein.

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
