OutBox purpose

[Pawel Salek <pawsa theochem kth se>]

Hi,

I wonder what is the purpose of OutBox in Balsa? Is it supposed to
store mails that for some reason could not be sent immediately? I
understand that the copies of the outgoing mail are to be stored in
sentbox/fcc? Correct me if I am wrong. 

I am just about to clean up the sending code and make it work and this
is the scheme I am going to implement so if you want to influence the
algorithm, please do it _now_.

Pawel
