[spf-discuss] redirect=%{l}

2006-05-22 10:32:50
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(_at_)ols(_dot_)es 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 "/"

This problem is not only restricted to batv as the allowed email
characters do not match dns allowed characters, so many email
addresses could then not be verifiable using something like
"v=spf1 redirect=%{l}._spf.ols.es", how is this addressed
by current specs and implementations ?
