Re: [swinog] Bluewin MX Protocol Errors
Hi I made this change as well. Let's see, what happens. But no TLS is not such a good solution… :) Cheers Alexander EveryWare AG Alexander Skwar Systems Engineer Zurlindenstrasse 52a CH-8003 Zürich tel: +41 44 466 60 00 fax: +41 44 466 60 10 mail: alexander.sk...@everyware.ch web: http://www.everyware.ch On 03.11.2015 10:23, Daniel Kamm wrote: Many thanks to Marcel Gschwandl, we are still investigating together the root cause for these problems.

Re: [swinog] Bluewin MX Protocol Errors
We were able to identify and reliably reproduce the problem in out testing environment, it is related to the TLS-Offloading which interferes with the traffic in some cases and brakes the communication with sending RSET commands and not handling the responses correctly. Thanks to all who contacted me directly and provided their logs and inputs, it was most helpful. As a workaround we disabled StartTLS inbound again and are working on a fix so we can re-enable it as soon as possible.
