[Plugin: Register Plus] From email address not using one specified in plugin settings

Hi,

Loving the Register Plus plugin. I am having one problem though. When a new user recieves a confirmation email after registering, the from address is my hosts mojitodi@box254.bluehost.com rather than the one specified in the settings mr.mojito@mojitodiaries.com. The bluehost.com one is treated a s spam with some people.

Any thoughts on how this can be fixed?
