If you aren't expecting that many reports to be sent in a single day... you could create a gmail account and use that to send the emails to get around having to force the user to configure an SMTP server. Not sure what gmail's terms and conditions are for doing this.
Here is a class which I wrote which sends an email using a gmail account...
Obviously there are some security issues here like someone could potentially get access to your gmail account. So, take that into consideration.
There are methods in this class to send the email synchronously or asynchronously.
