Hi
Lately we experienced heavy load on our mailservers. A few of our customers also get quite mailbombed from cablecom senders.
It looks like some single emails from a cablecom sender are being sent once from every cablecom mailserver ip out there.
Also emails from cablecom senders to our support system tend to create multiple support tickets as they also arrive in multiple copies.
Any others observing similar problems?
Example:
