ACK. That's the status quo and we're working with the hoster to (permanently) fix this. The platform itself consists of two mail servers for redundancy. Both have IPv6 addresses, but there's an issue with the failover IPv6 address that needs to be fixed and … communication with the hosters support on this leaves headroom for optimization. ;-) We'll reenable IPv6 support for list.sys4.de as soon as we've been able to resolve the issue. We'd like to get away from legacy IP better sooner than later. p@rick > > Op 09-04-2025 om 08:06 schreef Florian Piekert via Postfix-users: > > Hello, > > > > I only see IPv4.
