Hi All Just to give you an update on what happened here: - the old platform has been removed/migrated last fall; the A record has been removed in january - all active customers and domains have been migrated - we have no customer complaints - there are some customers, which haven't updated their DNS after several reminders (I suppose these are customers which decided not to continue with the service) - the technical people checked their config and are not missing any entries
-> so in short: customer / domain owner problem not Swisscom. Wish you a nice weekend, -steven -----Ursprüngliche Nachricht----- Von: <[email protected]> im Auftrag von Daniel Stirnimann <[email protected]> Datum: Freitag, 7.

So, I guess its a domain owner problem and not a Swisscom problem. For example, spital-lachen.ch used to have mtainXX.mailsecurity.swisscom.com. until June 2019 and has since moved to mxXX.mailsecurity.swisscom.com.
