Can't send Email with Mogul

[officerperkins]

Sorry if this has been covered before but I can't seem to get my Mogul to send email from my regular email account. Like your-username@bellsouth.net. I now have mediacom which looks like this username@mchsi.com..I have put the exact mail server settings as described on mediacom's web site. It will receive but not send. I have also clicked on the use secure ssl on outgoing messages and it still does not work. Can anyone help?
