<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We’re a medium sized regional MSO/broadband provider
with 200k+ mailboxes, strongly considering enabling SMTP authentication on our
customer-facing SMTP mail servers. We feel this is the next logical step
to minimize our users UCE/virus impact (we already tarpit, virus scan, UCE
scan, subscribe to RBL’s, reject prior to SMTP close). </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m looking for comments on whether this is generally
seen as a positive change or a waste of time (ie – will the next virus or
worm gleam your SMTP username and password from Outlook Express and use it to
replicate/SPAM)? </span></font></p>
