There are two ways to deliver mail. Either with this mailbox_command, or
by creating a pipe transport into master.cf and using it. You could try
if the transport way works better, see http://wiki.dovecot.org/LDA

I don't know what inserts the extra From_-line with mailbox_command
though. I don't think it's normal..

Anyway, I think this should also be fixed in deliver in some way. It
really shouldn't allow inserting From_-lines inside headers.
