Web server with 8051

Hi,

i would like to use web server with a microcontroller.

because i want to measure temperatures from temp sensors connected to a microcontroller and get datas by email.

What is the best microcontroller to use?

Is there already a microcontroller with web sever integrated?

i know well the 8051 and some Pics

Thank you

BeagleBone and Raspberry Pi both will serve web pages easily
