i'm having a problem, i can't send mail anymore. for some reason no matter what mail account i use in outlook 2003 it will not send mail (actually when i use the hotmail account it works, but if i use pop3 accounts it does not work) . so i assume it is a problem with the smtp port 25. anyone know how to fix this? I am using Outlook 2003 SP2, with Windows XP SP2. i have also tried sending mail with disabling my firewall, i have also scanned for viruses and nothing was found. someone please help out, thanks for your time.
