The below trimmed down code works with my ISP's email server. The 10 sec delay at the end probably could be shortned. As usual YMMV!
/*
SEND AN EMAIL WITH ARDUINO
9/23/11
This code was created by modifying the connect example from arduino.cc
and with the help of the YABB forums and their very helpful members.
This code sends an email to any email address and then disconnects.
