Yes. And the fallout is that generally this sort of RW activity does
not work well with LVS.
When such things are required, one reasonable solution is to have a
three tier setup where the lvs director load balances across multiple
servers (in your case pop/imap), which access their data via a highly
available shared filesystem/database. Of course this requires more
machines and more hardware.
