Hi all.
Why on earth is gmail checking the IP address of the message sender
(ISP assigned home address, for instance) against the sender's domain
SPF without the ability of checking if that original delivery was done
using SMTP authentication ( hence voiding the need for that IP being
part of the SPF record ) ?
I know its early i morning and I;m only just now taking my first sip of
coffee, but, err... this is what SPF does, checks sebder is allowed to
send as XYZ, smtp authed users sender from mail server and its in
senders domain, all fine there
Moreover, why on earth is gmail doing a SPF check ( that should ONLY be
done during the smtp conversation ) during a pop3 retrieval ?!
If there is anyone here from gmail ... fix that please.
That however is not fine, it should already have done the spf check, are
you certain it is doing it in pop transaction or just guessing?
Pasting a short snippet of your evidence might help someone take notice.
