Thunderbird does not ask for password when sending second mail !!!

>Potential security issue. If he forgets to log off when he goes to get a tea or a coffee, somebody can use his logged-in TBird session to send e-mails impersonating him. Sometimes the automatic >screenlock takes place after a few minutes. Window of opportunity for somebody to come and do nasty things. If you are in an environment where such activity is a risk (university, cyber cafe, >office area, hospital, you name it), then it would be nice to have an option to "always require password for sending mail". I.e. to disable the password caching mecanism.

Why don't you set automatic screenlocker down to 1 minute or even below? Then you don't have this "security problem" with any program.
