I must use AOL (9.0 Optimized) dialup to access the Internet from work. Once on, I use Outlook Express (6) to access 2 other non-AOL e-mail accounts. Am able to receive e-mail for these accounts via OE, but get a variety of error messages when trying to send mail. Have disabled ZoneAlarm, Norton AntiVirus and Norton Internet Security -- no change. Using WinXP Home.
