Cant send email

Hello
I can receive email on my iPad and on my windows laptop using a Tiscali mail address but have never been able to send email from either (If I need to send I use a hotmail ac). I have the hotmail ac out of sheer frustration. I have checked and re-checked the settings and looked on so many help websites but no help yet. Some get far too technical for me so i would like an easy answer if possible!
I am being sent spam/fraud emails which I would like to forward to the relevant people to let them know but I can't. Please help!
