Premature email sending, can it be fixed?

On this site some time ago and other blog sites, I have discovered people have a similar problem to me. It happened on my 3GS and now on my 4S. Emails are sent during composition. From recent experience, I am certain I am not pressing the send button - that is the common suggestion. One helpful idea is not to add addresses until the email is composed - Ok, unless you are relying to an email. Has anyone a tecnical fix to this issue please? Clearly life can go on with it but life would be easier without it. It happens maybe once every 20 emails.
