I'm guessing you mean the on the <= log line, 100 recipients
are listed. These are envelope recipients.

By "To field" I assume you mean the "To" header, as displayed by
some MUA. The header are different from the envelope. Exim usually
does not take account of the headers, and there is no checking that
they match the envelope.

It is possible that your mail client generated the message (including
headers) with the full set of 120 recipient names, but then only
passed 100 recipient names as the envelope-recipients with the message.

If you have +all, that is equivalent for this purpose to having
+received_recipients which is what matters for this purpose.

That does not answer the question. Does the mail client feed
Exim using SMTP, or by calling Exim as a program?

Those look like log lines. I asked what was in the queue.

The log there shows a bounce being generated. It should have
useful information. What did it say?

OK - this might not help, unless you have a single destination with over
100 addresses.
