Greetings,
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).
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)?
Is anyone aware of any well known mail clients that do not
support SMTP authentication (Unix, Windows or Mac)?
Thanks in advance.
