An unfortunate limitation of the SMTP protocol is it initially only
looks at the right-hand side of an address when connecting to a
server to send e-mail, and not the left-hand side. This means
[EMAIL PROTECTED] first passes through the same server as all of
the rest of [EMAIL PROTECTED] e-mail. A single high-volume or special
address can easily overwhelm the normal email infrastructure (i.e. mailbox
full) or the normal server administrators may make changes which affects
all addresses passing through that server (i.e. block by IP address).
Even the FTC's UCE [EMAIL PROTECTED] e-mailbox has had problems, which
affected the rest of [EMAIL PROTECTED] e-mail. So the FTC created a separate
right-hand side name [EMAIL PROTECTED] to separate UCE reports from normal
FTC e-mail channels which lets them route the mail with separate mail
handling policies based on the right-hand side.
