Is there any chance that the client tries to present you a certificate,
even if you do not request it?

I'm a bit suprised that Exim drops the connection (doesn't it?) seeing
the expired certificate, but this isn't very unlikely. I'd you a packet
capture to check the certificates from both sides.

    Best regards from Dresden/Germany
