Hello,
I cannot reproduce this, for me exim4 deals fine with this and retries
the message later.

I suspect you sent a message with a single recipient, but with
"multiple addresses int the To:" header. But similar to the address
inside a snailmail the To:-.header has no influence on the delivery,
the envelope information is the interesting part.

For proper testing this you could use
echo fooo | mail -s testing testadd@ress1 test@adress2

afterwards you'll find one of the addresse waiting in your queue
(mailq run as root will verify this) and it will be delivered at the
next queue run.
