What kind of email is it sending? Email accepted via smtp? What about 
system generated mail? Check that the symlinks are not still pointing to 
qmail. ls -l /usr/sbin/sendmail, ls -l /usr/lib/sendmail. If both these 
are pointing to something under /etc/alternatives then check those 
symlinks in /etc/alternatives. (mta-mailq, mta, mta-sendmail, etc)
