A properly written MTA should automatically handle issues like
this and re-split the envelopes as necessary. Sendmail will do this,
as will postfix. Dunno about Exim.
I think the problem lies somewhere with a locally screwed up MTA
which periodically won't respond at all, or can't get to its local
DNS, so stuff bounces when it shouldn't. But I can't be sure.
