Sonic email bounce due to blackholes spam filter

[http://dummy.us.eu.org/robert (Robert)]

I'm getting a bounce because this particular ISP is using blackholes.

Below is the relevant transcript.  Info seems to be available at
http://help.myway.com/mail/bounce/bounce5.html .

Could this be fixed so that I might email myway.com again?

Thanks!
