Well that's why you're getting broken hints databases.

Build 4.89 with the same DB you built 4.88 with.

So the SSL write failed, because the other side dropped the TCP
connection from under you. So the remote side barfed without a TLS
teardown.

Is the other side Exim 4.88 with its known chunking problems?

On the _remote_ side, if that's yours, then:

    # Bug-fixes 4.88
    chunking_advertise_hosts =


Much of the reason why we're releasing 4.89 so soon is that 4.88 has
some Issues.

Looks like known problems with counting bytes in chunking. The
remote side is Exim 4.88 isn't it?

I see no signs of a TLS problem, other than that TLS is what reported
the connection being abruptly dropped from under it by the remote side.
