And of course I have to correct myself: You want RFC4193's Unique Local IPv6 Unicast Addresses (ULA) [1]. I found them when stumbling across a thread about IPv6 troubles on this very list [2]. I was thinking about a workaround with some ifstated(8) triggered script re- populating tables with only one member each (i.e. the mailserver's new address). But then I couldn't even say if an address change would trigger ifstated(8)… Regards, Florian [1]: https://tools.ietf.org/html/rfc4193 [2]: https://www.mail-archive.com/misc@openbsd.org/msg142557.html
