it look like a something strange with libssl1.1 version 1.1.0f-4 and some of the certificates.
openssl s_client -connect mail7.hostmaster.sk:465 (and port 995) gives some buggy output (including connections with postfix or fetchmail), (older versions on libssl1.1 were OK), however, others like openssl s_client -connect kerio.comcraft.sk:465 are OK what do you think is the problem? michal On Sat, 12 Aug 2017 19:55:24 +0200 Sebastian Andrzej Siewior <sebast...@breakpoint.cc> wrote: > On 2017-08-12 16:19:08 [+0200], Christophe Troestler wrote: > > After installing version 1.1.0f-4 of libssl1.1 (and openssl), fetchmail > > started to report errors such as > > > > fetchmail: OpenSSL reported: error:14171102:SSL > > routines:tls_process_server_hello:unsupported protocol > > tracked in #768843 > > > and mbsync also started to fail with > > > > Socket error: secure connect to outlook.office365.com > > ([2603:1026:205:14::2]:993): error:141640BF:SSL > > routines:tls_construct_client_hello:no protocols available > > tracked in #871813 / #871765 > > > I had to downgrade to continue being able to fetch my mail! > > Closing the libssl bug as the issue is tracked in the leaf packages. > > > Best, > > C. > > Sebastian > > --
