[sylpheed:37070] Save to Sent an account preference

Hi,

While using Sylpheed is a delight most time, I am frustrated by the
option from Common preferences that decides whether you want sent
emails to be saved in Sent. This depends on which account I am using,
so I definitely need it to be an account option, not a common
preference.

I wonder whether this has been discussed before, and if so if there is
a good reason for staying it in the way it is. In this case I would
assume there is another way to do what I want.

In any case, thanks for Sylpheed, which, as I said, is delightful to
use.
