Hello,
I'm experiencing some difficulties when I send email to some reciepients.
The error which i receive in a NDR mail is:
Diagnostic information for administrators:
Generating server: www.hostnet.nl
customercare@hostnet.nl
mailfilter.hostnet.nl
Remote Server returned '<mailfilter.hostnet.nl #5.2.0 SMTP; 550 91.184.8.206 is not allowed to send mail from tsp-computerdiensten.nl. Please see http://www.openspf.net/Why?scope=mfrom;identity=info@tsp-computerdiensten.nl;ip=91.184.8.206>'
Yet i have a TXT record in my DNS which says:mailfilter.hostnet.nl
Remote Server returned '<mailfilter.hostnet.nl #5.2.0 SMTP; 550 91.184.8.206 is not allowed to send mail from tsp-computerdiensten.nl. Please see http://www.openspf.net/Why?scope=mfrom;identity=info@tsp-computerdiensten.nl;ip=91.184.8.206>'
v=spf1 include:spf.protection.outlook.com -all
i tried to change it as suggested by openspf.net to:
v=spf1 include:spf.protection.outlook.com a:smtpq1.gn.mail.iss.as9143.net -all
but i believe this is just enabling it for that specific server.
Any help would be appreciated.
