Outbound SMTP port to Internet is blocked from residental customers,
this is excactly why spam was relayed through a SMTP relay server.
All major Finnish ISPs block SMTP out because it is what Finnish
Communications Regulatory Authority recommends.

What difference would that make because 99% users who are affected by
spam proxy viruses store their username and password into email client
which makes those available to any viruses like SMTP relay server is.
