Hello there. I noticed that after migration, the "Additional IP addresses in CIDR format that deliver or relay mail for this domain" box contains both ipv4 and ipv6 IP addresses, as it should. However, if I edit that box and click save, it tells me that the ipv6 address listed in that box is invalid!
Double-check the IPv6 address and other IP addresses in the SPF record. If it says its invalid, it fails the IPv6 address validation.
Checked and indeed it doesn't work. Even with a valid ipv6 address entered into the "Additional IP addresses" box causes "Invalid IP address" error.
@till Just tested it myself on latest ISPC and Ubuntu. No problem what so ever. I can add and edit IPv6 and IPv4 addresses in that field without any problems (even subnets) @Turgut Kalfaoglu It must be an invalid IPv6 address causing the error message. You haven't told or shown us what you try to enter.
