If you have a system with multiple clients and any kind of load, then
all this logging is going to be quite volumous.

Oops, no. I meant "log_message", which is available in the ACLs. Oops.
It's all described in the ACL section of the manual. It doesn't require
you to recompile exim or write any "code", just add some stuff the to
ACLs, maybe referencing $smtp_command. And add a few extra hard drives
for all the logging.
The SMTP conversation is not particularly difficult to understand and is
very predictable. The existing error messages and log messages provided
in the default logging allow for easy interpretation of exactly where in
the conversation any errors occurred.
