I changed the doveadm config per the migration guide:

service doveadm { inet_listener http { port = 12354 } } doveadm_password = redacted

No where in the migration guide does it suggest using http there. I suggested

inet_listener doveadm {

Using http will indeed make it talk HTTP, so don't use http there.
