[swinog] cust.static.xxx-xxx-xxx-xxx.cybernet.ch not resolving

2014-12-09 Thread Mike Kellenberger
I am seeing mails that can't be delivered to mail servers with 
cust.static.xxx-xxx-xxx-xxx.cybernet.ch dns names because these cannot 
be resolved.


Anybody else experiencing the same thing?

Regards,

Mike

Had a similar issue a couple of weeks ago concerning former cybernet IP ranges 
used now by swisscom busniess customers. All their A and PTR entries got 
deleted from the Swisscom DNS Servers and replaced by slightly different 
entries.

Apparently those hostnames were not meant to be used as MX entries etc. 
because swisscom business customers have the ability to set own PTR records 
via customer portal and should do so.

Mit freundlichen GrĂ¼ssen
