Does that make any sense?It makes sense, but that's a different error than the one you got before. This new error looks like a Roundcube configuration problem, having to do with either its connection to Dovecot or possibly a back-end database server.

(MySQL?)MariaDB. Now it's time for me to clarify. The "source stream returned no data" error is in Evolution; the "connection to storage server failed" is in Roundcube. So I'm seeing similar errors in two different email clients trying to get to the same server. I know there are any number of reasons for a failed connection to Dovecot, but I just don't have the experience to figure this one out. Ken
