Hi Guys
Is there a UPC mailadmin following this list? It appears as if there is an issue between your SPF and DNS configuration. Please contact me off-list for further details.
Many thanks Beat

Also, the return address for billing bounces:

Are you getting emails saying you double paid your UPC bill / Sunrise Bill / Swisscom Bill? I have seen some phishing attemts lately like this. some are like "you paid twice click this link to refund: [button named "pay bill here"] ".. doesnt makes a lot of sense ;)...

First, this may actually not be a domain that UPC controls, but it is where the invoices are sent from (beware, there are some spams out there that mimic invoicing or refunds, but this was not the problem here).
As I contacted UPC through various means during the last month (including registered postal mail :->), they finally replied by e-mail today and they have solved the problem I raised on the 27th of December.
No idea if the mail to swinog sped up the process or not.
However, they did not comment if their invoice provider fixed, or not, this e-mail address issue or not.
Thank you for the various replies I got through the list.
