Hi Paul,<br>
<br>
a fellow Groninger? Then lets try to help ;-)<br>
<br>
From the OSX v10.11 release notes (released 15-8): <br>
<ul>
<li>DHE_RSA cipher suites are now disabled by default in Secure
Transport for TLS clients. This may cause a failure to connect
to TLS servers that only support DHE_RSA cipher suites.
Applications that explicitly enable cipher suites using
SSLSetEnabledCiphers() are not affected. Safari may display a
“Safari can’t establish a secure connection to the server” error
page. Safari and other clients of CFNetwork API (NSURLSession,
NSURLConnection, CFHTTPStream, CFSocketStream and Cocoa
equivalent) will show a “CFNetwork SSLHandshake failed” error in
Console.</li>
</ul>
<br>
Maybe you can use checktls.com to find out which cipher your site
uses. A very useful site. <br>
If your site uses a DHE-RSA cipher, you may need to change the
tls_cipher_list in your imapd.conf <br>
<br>
