Exim looks up the MX from scratch every time it does a queue run,
although your nameserver infrastructure may have the old data cached.
In general, every time it makes another attempt at a message Exim
re-routes from scratch every undelivered top level address (an address
that shows in eg 'mailq' output). Looking up MXes again is one aspect
of this, but it will also do things like re-expand aliases and so on.
