Mail Crashes when sending

Which Security Update?

Try this:

1. Go to Apple Menu > System Preferences > Accounts, and create a new user account for testing purposes.

2. Either log out of your main user account or just quit Mail so that it does not interfere with the other user account.

3. Log in as the newly created user and set up Mail anew there. Does the problem happen there as well?

I created an account and mail works fine over there but on my own account it still crashes... what should I do?

Did you ever get an answer to this? What to do next?
