I think that your statement: > Other email clients I just tested on my phone (myMail and > AquaMail) are also not able to communicate with POP3/SSL at HC1 > but work fine with HC2. would seem to confirm that this is not a K-9 specific issue. I suspect that android-6 dropped SSLv3 from its supported encryption protocols (I couldn't find a detailed enough list of android-6 changes to confirm this) and that that's what your HC1 provider is still using (without support for TLS). If you're using a *nix machine you can use "s_client" to poke at their POP3 SSL and see what protocol(s) they are supporting. You might also try asking them. They should be using TLSv1 (and above). They should not be supporting SSLv3 (or even TLS < v1), even as fallback. I haven't had any issues with my nexus-5, stock android-6, K-9 5.107. -- -- You received this message because you are subscribed to the K-9 Mail Users List.
