Hmm, don't recall exactly, but IIRC the outgoing mail filters are not
applied *before* sending, thus is not possible.

There is absolutely no point in doing this. Evolution will *not* send a
mail on its own. Every mail that will be sent will be willingly done so
by you.

Also, this is a task to be performed on the MTA level, rather than in
every single MUA. If you really feel like you have to filter *outgoing*
mail for viruses (or spam), you should do this on your own SMTP server.
