I was using imail to automatically download mail from my gmail account when I was at school. Now I am at home for the break, but my home has a modem connection and now i receive mail automatically just as before, but I can't send email messages out??? must i change the port, since the mail client is linked to gmail, what could cause me from not bein able to send mail out. Since I have switched from an ethernet connection to a modem connection, what setting in preferences must I change to rectify this issu ????

-thank you
