A while ago I asked advice on Email programs and I decided to use Thunderbird for my parents computer and my girlfriends. Everything worked great the first day, but now either of them cannot send emails. Thunderbird downloads the emails that are sent to them, but if you reply or try to send a new email it says something to the affect "The message could not be sent: negative vibes from (their email address). It is the exact same problem on both pcs.
P.S. I am also. which I believe is required, using the aol and hotmail extensions along with the webmail extension.
Can someone help me? I'm tired of tinkering with it, tried a few different things and nothing works.
