If I recall correctly that's a massively helpful error coming from
GnuTLS - is that what you run?

For workaround you could avoid advertising STARTTLS to that IP.

Or, to investigate, set up for a packet capture of connections
from that IP - and ask the gnutls-help mailinglist. They'll
want to know what library version you're running;
"exim -d -bV" should tell you.
