In the main part of your config file:
rfc1413_query_timeout = 0s
That stops the Exim receiver process from doing any ident lookups and
will remove, completely, your "U=" bit of logging.
It still isn't relevant. And you still haven't done as asked, or
suggested, by various posters, namely:
1. turn up your logging ( -d +all, or log_selector = +all )
2. post your ACLs (or more pertinently, the full config where relevant)
3. run in session test mode ( -bh ip.add.re.ss ) with debug ( -d +all )
3. try another angle of attack such as strace
