Ano, pred nejakou dobou byla na relay.globe.cz. (alias smtp.post.cz) pridana restikce podobna jakou pouziva VOL - autentifikace pres POP3 a otevreni SMTP pro danou adresu na omezenou dobu.. Ale to stejne neresi jednu vec - u zadneho freemailu - pokud si totiz spammer zalozi zdarma konto, muze toto omezeni jednoduse obejit - proste tim, ze si vybere postu se sveho konta a az pak zacne spamovat.. Ale tomu se uz jednoduse zabranit neda..
