I need a solution
Hi.
I need your help... i cant send mails to *.messagelabs.com.
Our domain is MCC.CL and we cant send mails to domains: btgpactual.com and cl.engie.com.
Our MX and SPF are fine....
We always get the message:
#< #5.0.0 smtp; 553-SPF (Sender Policy Framework) domain authentication> #SMTP#
I'll be waiting for your response
Regards.
