[Pkg-openssl-devel] Bug#871477: upgrade of libssl1.1 to breaks dovecot imap via tls: kmail from debian stable/unstable cannot connect to dovecot any more

Tue Aug 8 10:44:09 UTC 2017

Package: libssl1.1
Version: 1.1.0f-4
Severity: important

After upgrading a server to libssl1.1 1.1.0f-4 kmail on debian/stable could not connect to dovecot on debian/unstable any more (kmail on debian/unstable can't connect, either).

Dovecot logs "... tls_process_client_hello:version too low ..."

Probably this is due to "Disable TLS 1.0 and 1.1".

Please reactivate it. We would like to continue our policy to continously test debian/unstable and debian/testing on servers in our environment.
