[exim] interessting misconfiguration @PayPal.com

Hi guys,

paypal seems to have a "small" problem to maintain it's servers with the
same patch level:

2018-03-11 13:47:14 1ev0Nd-0006bI-Ss <= service@???
H=mx0.slc.paypal.com (mx2.slc.paypal.com) [173.0.84.225] P=esmtps
X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no S=39287
id=1520772431.8210@???

2018-03-11 13:48:02 1ev0OO-0006e9-4U <= service@???
H=mx1.slc.paypal.com (mx2.slc.paypal.com) [173.0.84.226] P=esmtps
X=TLSv1:DHE-RSA-AES256-SHA:256 CV=no S=41659 id=1520772477.30184@???


Those two messages arrived on the same server system, so our part of the
connection was the same. There is no reason to have on connection TLS 1
and the other TLS 1.2 without a misconfiguration at paypal's
maiservercluster.

Can anyone confirm similar sightings on your servers?

best regards,
Marius
