Hi guys
I get reports from customers sending their outgoing mail through smtp.swisscomdata.ch stating their mail is bounce due to SPF violation. It seems the IPs of the mailservers processing those messages have changed recently.
Is there anyone from Swisscom mailserver team who could provide me with a list of IP of outgoing SMTP servers used to relay mail sent to smtp.swisscomdata.ch? It appears that IP ranges 46.14.34.0/24 and 46.14.97.0/24 are involved. I'd like to update the SPF declarations for those customers...
Cheers
Jean-Pierre
