Hello,

I've just sent out grade for HW#5 and the HTTP extra credit assignment.

A quick note on the SMTP component of HW#5:  as you follow the example
from the lecture slides in sending email by telnetting to the mail
server and issuing the commands manually, you need to make sure to
understand what each command means.

In particular, read up on what the point of the 'helo' command is.  This
command is not there for decoration only, and some mail servers will
actually react to whether or not you provide the correct command here.

Research what this command may be used for and think about how a mail
server might use the information provided in this command, for example
when applying spam defense mechanisms.

-Jan
