I can login fine to my webmail installation and the database is set up great.
I can receive emails into the mailbox and it shows in roundcube, but i cannot send any messages. Have i missed something in the installation?
I'm running php5 and mysql5
i am experiencing the same issue
Are you sure your SMTP server works properly?
did you set it up correctly in roundcube's configuration?
I had this problem too--even wiped out my old and started fresh. No identity was shown in the drop-down box, either.
I found this thread and fixed it immediately:

Hope that works for you.
