Right, you're running out of space by trying to send too many
CA names.  It is better to have this fail, so you can figure
what is trying to dump your entire trusted CA list (of names)
to the server, than to actually have that silently "work".

Now you need to find out why that's happening.  Perhaps your
"openssl.cnf" (Linux distro mistake?) causes the damage
for all applications even without explicit code to that
end in Exim?  Or you're calling something to make it happen.
