Rather than trying to draw increasingly complex diagrams in ASCII, I've put some here (without the LVS layer): https://walnut.gen.nz/mail-architectures.png
I've come up with a revised plan - I think we can do without LVS; SMTP should just work with multiple MX records, and IMAP/POP should be fine as well with RRDNS - the machines should be up most of the time, and if a customer has to click to reconnect every now and then on the rare occasions when they're not it's not a huge deal. Otherwise, we could also do load balancing on our routers.
Anyway - any comments on the sanity of this diagram most welcome :-) https://walnut.gen.nz/mail-architecture-2.png Richard
