It should call back to the host that Exim gets from its routers. That
*may* be from an MX, but it depends on how your routers are configured.
What is the output from "exim -bt user1@???" ?
However, that log line doesn't show that a callback failed. All it says
is that it couldn't verify that address. This could be for several
reasons - e.g. it couldn't look up the MX records. 151.99.250.40 is the
*sending* host, not the callback host.
