If you do know how to send SMTP commands "by hand", you can do a simulated
SMTP session from 165.165.192.254 with full debugging output by using
| exim -d -bh 165.165.192.254

Of course; you _do_ send mail from your provider's gateway IP.

That user is not authorised.
Do you accept all mail from your provider's gateway IP, 165.165.192.254,
i.e. is that IP address static and just used by yourself (or others who
may use that exim server as smarthost to send their mail)?
If that's the case, you can use
| /usr/sbin/exim_checkaccess 165.165.192.254 email@??? -f jeff@???
to test if that works.
Or do you authenticate by sending username and password via SMTP-Auth?
Nothing *should* have changed during the upgrade.
