Hi, Currently, I cannot send emails to the domain xtra.co.nz. This behaviour started a couple of days ago and prior to that, it has been working happily for years. When sending an email, I get the response: Reporting-MTA: dns; smtpauths.lb.bluewin.ch [195.186.227.133] Received-From-MTA: dns; xxxxxxxx [y.y.y.y] Arrival-Date: Sat, 21 Nov 2020 11:45:06 +0100 Final-recipient: rfc822; *E-Mail placeholder* Diagnostic-Code: smtp; 550 5.7.1 Message rejected due to SPF policy Last-attempt-Date: Sat, 21 Nov 2020 11:46:12 +0100 Other recipients on the CC list receive the email without problem and when I send an email from my GMail account to the xtra.co.nz domain, it also arrives without problem so this looks like a Bluewin->Xtra issue only. Any ideas as to how I can resolve this? Thanks and regards, Robert.
