Hi there, I have a strong suspicion that this is SSL related.
I've found that this does not work: openssl s_client -connect example.com:993 [...] 139765775537472:error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small:../ssl/statem/statem_clnt.c:2149: [...] but this does (found here: https://imlc.me/dh-key-too-small ): openssl s_client -connect example.com:993 --cipher 'DEFAULT:!DH' Now the received wisdom is that this is because of OpenSSL configuration and you can fix it by adding this to /etc/ssl/openssl.cnf: [system_default_sect] MinProtocol = TLSv1.2 CipherString = DEFAULT@SECLEVEL=2 However, that does not seem to work, either for the OpenSSL command line or for Akonadi.
