Hi, I upgraded my dns servers to 188.8.131.52 (and also the main ispconfig server). It seems that there is a change in the handling of "empty" name in the rr records. Specifically, I have many zones and thousands records which have an "empty" name in the rr. they were automatically substituted for '@' until 184.108.40.206 Now, they're left 'empty' and named complains failing to load the zone. The problem is caused by the 'MX' record, which in my case is: <empty> MX 10 mail and should be @ MX 10 mail. If I try to add '@' in the gui, the gui will not allow the '@' symbol in that field. I think that the '@' symbol should be allowed on RR. ispcomm.
