I have monitored Florian Weimer's attempts to debug. The main stopper seems to be that it is extremely hard to get ahold of Master's logs. > The situation on my mailserver was that the primary MX had a long term > unavailability and was way past cutoff time, but the secondary MX worked > fine.

If you experience this for the next time, I'd like to see the output of exinext $DOMAIN. > I think this is a serious bug, as it can cause mail to get lost > (bouncing a mail for no good reason at all in some very common > situations like the IPv6 vs IPv4 multimhomed MX's) Agreed. But since the bug doesn't happen for me, I need cooperation - either yours or DSA's to be able to Debug on master.
