The best library in the country, Matica Srpska, sent on my request a copy of a book page i needed badly.My server Nodnet.yu, using sorbs services, blocked their E-mail as spam!At the same time, EACH day I receive 40-50 SPAMS in my inbox (same server !) and they were so cheeky to inform me that some 15 spams are kept in their archives, which I suspect are important messages to me.They refused to send them upon my telefone rquest.Earlier, some emails to my brother in London, my good friend in NY etc.were returned by their Mailer Deamon.What could I do?
