Your most recent questions to this list have been of the "did you try
this before mailing the mailinglist"-kind, but hey, we've all been
there!
The "I=..."-flag in log lines indicate what port Exim received the
message on. The "P=..."-flag indicates what protocol was used and
the "X=..."-flag shows the ciphers involved.

I=[10.0.25.2]:465 P=esmtps X=TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256

You might want to take a peek at the log_selector configuration option,
or
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-log_files.html
in its entirety. It will explain a lot about Exim's logfiles to you!
