That shouldn't be causing you delivery problems, that's just Exim logging certificate validation errors - either self-signed, or an unrecognised CA, or similar. I would surmise that if you look at the other entries for that message ID you'll find that it delivered just fine.
Likely candidate for that log message would be:
commit 6d580f19f4a7981174e492a40b32a5cb22fca8f9

Log certificate verification status by default
...which was included in 4.85 and above.
Of course, if you're seeing some other behaviour, the additional log lines would help :)
