i just picked up a n810 and want to do something useful w/my 770 currently running 2007HE

some questions
1. is it even possible to create a mail server on the 770 running 2007HE? do i need to downgrade to 2006?

2. i control a domain and i am the only user so the volume of mail should not overwhelm the tablet

3. i am a relative linux newbie so i need good instructions as to how to do this- where can i find a faq if it is possible

4. am i asking too much to put up a webpage as well on the 770?

any suggestions are appreciated

tia
