Hi !!

Just playing with BATV i noticed that it could conflict with
some (mine in that case) SPF setups. If i publish SPF records
like "v=spf1 redirect=%{l}._spf.ols.es" which use the local part
of the envelope sender to generate a new dns request then batv
encoded addresses like prvs=david/0297929b3b@??? produce a
dns query on prvs=david/0297929b3b._spf.ols.es which include
two forbiden charactes (= and /) I noticed that some implementations
will just use david/0297929b3b._spf.ols.es for the query but this
also includes the forbiden character "/" Taking apart the obvious
problem with %{l} (allowed email characters do not match dns allowed
characters), it will be nice to be able to change the way exim
generates batv signatures

PD: Please avoid answers like SPF is broken or why do you want to
use SPF.

Thanx & best regards ...
