Hi Ken, > But when I tried to set up imaps this way, I got the error > "failed to create TLS stream: Unknown error -87".
This error is reported by the gnutls library. It stands for "No supported cipher suites have been found."[1] This means that none of the cipher suites offered by the server[2] is supported by the client and vice versa. Regards, Sergey [1] https://gnutls.org/manual/html_node/Error-codes.html#Error-codes [2] configured using the tls.ssl-priorities statement.
