APOLOGY.smtp

$dude,

Apologies for the noise.  Aaron works with me on a research project
to map the core of the Internet (i.e., not near your SMTP servers).
Such a map will be extremely useful in understanding large scale Internet
behavior and future Internet engineering projects.  You can check out the
details at our project website http://www.cs.umd.edu/projects/sidecar .

We have done everything we can think of to limit the load and
intrusiveness of our experiments, for example, we rate limit the
connections and make the smallest smtp session possible with just a
HELO followed by a NOOP and a QUIT.  No mail or spam are sent in our
connections, nor do we probe for valid e-mail addresses.

If you let us know which servers your administer, we can remove them
from our lists so that we don't bother you again.

If you have any additional comments or concerns, please feel free to
mail me.

Apologies again,

- Rob Sherwood
