I had a lot of problems with my email. Receiving spam, provider who accused me of sending spam, not beiing able to make a good connection with pop3 and smpt. After i changed my password everything worked fine and the amount of spam was only about 10% of the usual load. What does this tell me????
I work with Windows XP, use MS-Outlook, McAfee AV on my PC (Antivirus + patches Micrososft up-to-date), have my PC behind Ositus Winproxy (on Win98 machine) who's Antivirusprogram told me often about my PC sending OR receiving a file with Exploit/Eframe or W3p/Netsky.P.worm. I could not trace both on my machines. On my home-network are 4 more PC's with all users only using hotmail.
Because of the troubles I performed on my PC and de Winproxy machine an extra scan with online virusscanning software adn firewall-testing stuff. All fine. I decided to use internet-mail, changed my password and suddenly my pop-up account inmediately worked fine.
