I have tailed the system.log on our Xserve (records authentication
events) to see if there is any delay server-side. The authentication
(presumably for rcmail_imap_init) happens immediately, so it appears
to be something within the webserver or Roundcube.
Anyone else experienced this?
My roundcube connects to an IMAP server on the LAN without SSL, TLS or encryption and I do not experience any such delay.
Maybe this helps you,
