Topic: Domain with bloated DNS records required for testing/verification purposes

[chris burnat]

Does anyone know of an active email address associated with a domain known to have bloated DNS records to facilitate verification of Bug #3827? 
If an "ANY" lookup of this domain returns more than 512 bytes, then qmail logs reports :
"deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/"
I have scouted the forum to no avail for a suitable address, any help would be great.
The owner of this domain should not mind receiving a couple of test emails.
For additional info, please check:

Thanks.

I had the same problem with my server

server is in "server only" mode and act as mail server + ocs server
due ISP restriction I need to use only one IP and I need also several VPN tunnels between branches which was initially implemented with ZyXEL ZyWALL series routers and I have secondary provider for backup of internet connection ....
because of all of this the server works behind of an ZyWALL 35 UTM [firmware version V4.03(WZ.0) | 11/07/2007]

initially the mail server wasn't able to send directly the emails to other servers
everything was strange
after a week of work around I found for moment the solution to delegate mail sending to other email server (which I administrate) with user/pass login (delegate to ISP SMTP server)

recently I discovered that error on the server :

"deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/"

and I realised that the problem came from DNS
initially I used the ZyWALL as DNS relay (there I can set more than 1 or 2 DNS servers - right now I have 6, and also I have several "internal zones" implemented for users already in VPN area)
after I changed the DNS in SME server with one of my ISP emails start to be sent directly without any problem
and the error disappeared from logs

I think you can use one of this routers to simulate the problem
