Hmm, I dont know that option, maybe the premium edition team added that and it trickled into the open source documentation. Iirc by default syslog-ng made sure compression happens within tls as long as the other party supports it.

Or you want to disable it?

Hi all,

According to this https://www.balabit.com/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html/tlsoptions.html

Allow-compression() should be a working option under tls.

I did google on this a lot and found no config snippet which shows allow-compress() to be working and to my surprise when I tried to include it in my config I get syntax error ___________________________________________________
