I have had a previous request to control the number of simultaneous
connections to certain hosts (for use over slow lines) but even if/when
I provide this it wouldn't help you, as exim would still send all the
pending stuff over one connection, presumably.

This could be done by kludging up a "delivery failed, next retry time =
a long time ahead" record in the hints database, but there isn't a way
of doing that at the moment. (The exim_fixdb utility can only modify or
delete entries, not create them, and anyway, its interface leaves a lot
to be desired.)
I have noted the suggestion. I think I would implement it as a new
utility rather than screwing this rarely-required feature into Exim
itself. A more comprehensive "manage the hints databases" utility would
be a good thing in general.
