Hello,

 

I have a problem

Emails sent at secondary address (@hotmail.fr) are not received:

 

[65.55.92.168] #<[65.55.92.168] #5.0.0 smtp; 5.1.0 - Unknown address error 550-"SC-002 (SNT0-MC3-F8) Unfortunately, messages from 81.252.179.235 weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors." (delivery attempts: 0)> #SMTP#

 

 

It's OK if they sent at primary address (@outlook.com)

 

Thanks for your help.
