The system in question is running with queue_only = true to take
advantage of the two-stage queue running process invoked by exim -qq.
Most of my setups use real mailing list software which batches up the
outgoing mail into many messages with a few hundred recipients each.
The current case, where an alias is used to expand a single address
into a list of 20K recipients, is a "first" for me and I was
dumbfounded by exim not having delivered to the first thousand
recipients after an hour.
Unfortunately, the system owner decided to replace exim with postfix
before I found out about remote_max_parallel. Postfix delivers to all
20K recipients in like five minutes.
