I'm trying to get my head around this issue. My emails are getting sent into spam for people. In this case, its gmail. If I look at the email details I get:
109.74.201.130 is another server, which hosts ultranerds.co.uk. This is the SPF record I have for the domain clickpress.com:
...and here are the email details I'm sending:
From: [email protected]
Subject: Your ClickPress news release has been approved
To: [email protected]
So why on earth is it trying to lookup the IP for ultranerds.co.uk, and doing the SPF check on that? I thought the whole point of SPF was that it looks up the SENDERs info, not the RECIPIENT??? (I've never seen this behaviour before)
