Absolutely agreed!  I wasn't questioning their listing in the RBLs.  I was just wondering out loud if anyone had 
tried to convince Myway to fix their ways.

Personally I have no qualms about dropping these emails, but you know

This is now what I have done on an individual user basis.  There is no 
way I would whitelist the whole of myway.

I generally try to avoid whitelisting if at all possible as I think it 
is a very blunt instrument and without SPF easy to fool, and adds an 
administrative overhead.  On top of this I use SA via MailScanner so at 
the moment any whitelisting was done through the MailScanner rules, 
which provided me with consistent log analysis, adding a 
whitelist_from_spf into the SA config messes up the reporting and 
creates another file that needs maintaining.

I could whitelist these addresses in the standard MailScanner method, 
but I like the idea of the extra protection against fraud that SPF provides.

This is what I am doing now.

Hmm!  I would love to do this.  I doubt whether my user would be happy 
to move him and his family.
