[exim] SSL verify error / certificate has expired

Hi,

i see a lot of " SSL verify error" with "certificate has expired"

like:

2016-04-08 05:09:02 [1284] [91.151.213.114] SSL verify error: depth=0
error=certificate has expired
cert=/C=US/ST=Virginia/L=Herndon/O=Parallels/OU=Parallels
Panel/CN=Parallels Panel/emailAddress=info@???

Is there a variable inside exim to match with a reject in an ACL?
Would help to prevent the receive of a lot of SPAM coming from badly
maintained and exploited CMS Servers.

Thanx
