Hello

If you are using imapfilter 1.3 then you should read the documentation
that comes with that version.  I'll explain to you what I mean...

You are mixing configuration of 1.x versions with the newer 2.x.
Version 2.x can understand old 1.x config files but not the other way
around.  Also, you can't mix the two.

The second line inside the function filtrar() should be:

  flag(account1, 'INBOX', 'add', { 'deleted' }, r_spam)

This is the correct format for 1.x, instead of the mark_deleted() you
use, that is part of the new syntax for 2.x.

But keep in mind, that when you move() messages to another mailbox, they
are by default marked deleted in the source mailbox, and thus, you don't
really need to flag() them.
