I think this is more of a question for the Google Community Forums. What McAfee product are you using?
Dear Users, Has anyone come across this message? ''Google tried to deliver your message, but it was rejected by the server for the recipient domain by . The error that the other server returned was: 550 5.7.1 has been blocked by summerdemand. Would anyone know how to resolve this error as external users are not able to send us any emails.
I also reduced your headline so it now fits.
Thank you Ex_Brit. I am new here
I am using Mcafee VirusScan+Antispyware Enterprise. Is that a virus blocking the emails or something? I have never heard of ''summerdemand''.
OK I moved this provisionally to Business > VSE for better handling, let's see if anyone here knows anything.
Thank you Peter.
