looks like i should have searched harder as i think i found the solution in this post
http://forum.nginx.org/read.php?11,16398,17787
all i had to do was amend the rewrite config location @rewrite { rewrite ^ /index.php; to the following
location @rewrite { rewrite ^(?!(/roundcube/)|(/phpmyadmin/))(.*) /index.php;
this now means clean urls are working for drupal and roundcube & phpmyadmin can also be accessed as required
mods, please mark as solved/closed
thanks
