Assuming Debian, delete everything in /etc/exim4 and say β€œMartin, can I have your minimum useful exim4.conf, please?”
The problem with exim4 and Debian is that the magic configuration tool produces insanely complicated config files even for the simplest setups.
I generally use the debian exim config for basic mid-flow machines (i.e. not internet facing ones) and we have custom exim config for our incoming mail servers and mail backends; and our outgoing server is postfix, though I am not sure why @rjek picked that.

Aah yes, exim's default approach of "woah that's a lot of mail, Imma wait a bit and see before I send it all out"

That can be a perfectly sensible way to deal with bulk mail submissions. It’s a default, not a hard-baked limit.
