I have found the problem. A small patch for 1.82 is attached below. The
problem will strike only when
(a) remote_max_parallel is set greater than 1.
(b) There is a queued message containing two addresses with different
host lists, but sharing a common host somewhere in each list, and the
message was previously routed so its hosts are listed in the hints
database.
(c) Another message is delivered to the host that is in common.
The effect is that Exim wants to re-use the SMTP connection for the
queued message, and stupidly tries to send both copies of the queued
message in parallel.
