Does the roundcube instance use the DNS name or the IP address of the IMAP server. Does "host your-server-name" return the IP of the server? > So I figure the problem was with the connection to the server and the > resolution of the server name etc...

I'd guess it is a DNS issue [although, in my experience, TB3 is a really buggy app - so who knows]. If you are on LINUX try it with Evolution [a good IMAP client] - does it work from there? -- openSUSE w/GNOME <http://www.opensuse.org/en/> Linux for human beings who need to get work done. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
