Just side note - you need not to wait for a source patch. Just disable TLS for those destinations as a instant workaround. Users of 8.4/9.3 need to disable TLS to those destinations supporting TLSv1.2 only (as TLSv1.2 is not supported by sendmail on 8.4/9.3-R), so you will not be alone with such kind of workaround ;-) Dan
