Roundcube offers the option to enter multiple default hosts that are presented as drop-down list. This plugin adds a somewhat simple functionality to preselect the correct entry from that drop-down by matching the entered email address.

This plugin just adds a litte javascript code to the Roundcube login page and it is optimized for use with the Elastic skin, which was introduced in Roundcube 1.4.0.
It might work with previous versions, but do not expect it to. You should use the legacy plugins for older Roundcube versions.

This plugin is an overhaul of the plugins from neurodeamon as he doesn't continue to update them.
