Hello,
I sent an e-mail to several recipients, but I got a blockade from one of them, claiming:
msfrf2206 rejected a message that claimed an envelope sender address of [my mail adress]@xoxy.net.
msfrf2206 received a message from mail-3y.bbox.fr (194.158.98.45) that claimed an envelope sender address of [my mail adress]@xoxy.net.
However, the domain xoxy.net has declared using SPF that it does not send mail through mail-3y.bbox.fr (194.158.98.45). That is why the message was rejected.
Contact the xoxy.net postmaster and tell them that they need to change xoxy.net's SPF record so that it authorizes mail-3y.bbox.fr. For example, they could change the record to something like
v=spf1 mx ip4:216.75.62.81 ip4:216.75.62.102 a:mail-3y.bbox.fr -all
(I changed my real mail address by [my mail adress]@xoxy.net in the post).
Could someone help ? Thank very much in advance.
