It looks to me as though there is a routing problem - probably
asymmetric - between your host and theirs. Can you traceroute to
their systems - where the traceroute stops may well be near where the
problem is. Are you pushing traffic down a route which your upstream
provider does not support. Is someone using RBL over BGP routing and
blocking things out...
Almost certainly not an exim problem - if it was exim you would at
least get a banner back telling you that exim isn't interested.
