Upgrades are always *possible*. You just need to be sufficiently
motivated. Which is more pain, rejecting the mail, or doing the
upgrade?
Another option is to point the mail at a different server, which
is upgraded, or at a proxy that performs the same sender "address"
(what the application sends is not an address) transformation.
