Since my phone updated to Marshmallow yesterday, I can no longer get
secure email connection from my Nexus 5 phone to the POP3 server at my
hosting company (call them HC1) - 4 accounts on two different hosted
domains on the same POP3 server. When configuring the
connection/account, I get "Cannot connect to server. Handshake failed".
If I go ahead & finish the config (adding a SMTP server), then the Inbox
in the folders view in K-9 mail shows "SSL ProtocolException: SSL h".
Yet a POP3/SSL connection is still working ok with K-9 mail to an
account on a different hosting company (call them HC2). And Outlook on
Windows 7 still works fine using POP3/SSL with hosting company HC1.
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.
I'm pretty certain it's not K-9 mail issue, but my hosting company
simply says there's nothing logged in their log files, therefore there's
nothing to investigate.
One thing Google did in Android 6 was move from OpenSSL to BoringSSL:
http://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client
This could have potentially dropped support for SSLv3 (I haven't found
anything definitive). If HC1 is using SSLv3 (flawed in many ways) that
could be the problem. Frankly, there's just not enough information here
to be able to make that determination.
