I need a solution
One of my staff is unable to send email to the particular email address. It just bounces back with the error message like this “cluster1.us.messagelabs.com #<cluster1.us.messagelabs.com #5.0.0 smtp; 553-SPF (Sender Policy Framework) domain authentication 553-fail. Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1)> #SMTP#”.
IT hasn’t been an issue last two years just happen from last week.
Can someone help me with tha one?
Thanks
