Anyone an idea about what is going on and how to solve this?
Searching for the error already gave me a few suggestions, like that I have an open relay, so I edited my postfix main.cf, to cntain a few lines with restrictions like suggested on this forum: http://ubuntuforums.org/archive/index.php/t-2060287.html , but still the same problem.
Was this indeed my problem and do I need to give it more time, or should I fix something else?
It indeed seems to be a blacklisting problem, I suggested a recheck at yahoo so I will wait this out for now.
Another questions, for a new domain, another VPS, I receive this error message:
"
Delivery to the following recipient failed permanently:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomain.com by srv5.myhostdomain.com. [IP.AD.DR.ES].
The error that the other server returned was:
