Subject: [exchangelist] Sender ID filtering
http://www.MSExchange.org/
Having recently installed Exchange 2003 SP2, I thought I'd have a look
at the Sender ID filtering. It seems to me that unless you can be sure
that all domains that send you email are legit and have valid SPF
records then this can not be safely used. Or am I not understanding this
correctly?
Does anyone have any figures on how widespread usage of SPF records are?
Is anyone on the list using Sender ID? Any comments, problems etc?
