Hi List
Today 12:00 3000 UPC Email accounts were migrated from one email platform to another.
DNS TTL was set to 300s about 1 week ago.
Looks like the change of mailserver IP has not yet been propagated to the UPC DNS servers that is being used by those customers.
upc.ch has SOA record ns1.cablecom.net. hostmaster.cablecom.net.
----- Transcript of session follows ----- 550 5.1.2 hostmaster@cablecom.net... Host unknown
If anyone could hint the UPC hostmaster to please PM or better call me.

Hi List
We start seeing more and more logins from UPC IP addresses. So it looks like the change got propagated now.
