And I'd agree with that, if exim would not try to deliver to
mailbackup.inode.at (after a temporary error for user@???) at all.
But it only does not try the secondary MX if the primary MX failed "for
a very long time"(tm). And that gives very bad behaviour with a
greylisting MX and a not-greylisting backup MX. (Besides that being a
very stupid setup, yes.)
