It looks like you typed your question into the search box, at the top of the page, instead of entering a title into the question box. That resulted in AB's server finding an old post of mine (from 22 December 2006!), which was irrelevant to your question anyway.
We're now getting closer to understanding your problem but you've still not told us which email program you're using (e.g. Outlook, Outlook Express, Windows Live Mail, Thunderbird, etc) or whether you're actually using a web-based mail system (accessed through your web browser) and, if so, which one.
