Thanks again Fabio. I'm looking into the sensible-mda issue. Some software I installed insisted on having sendmail installed but I have just removed that and also sendmail in case that's part of the issue. I'm also looking into Lucky Backup which creates a cron job that might cause email noitification issues.
With regard to the Virtualbox issue, I'm using Oneiric so perhaps that can't be solved?
