Where would that leave backup MX records?  My private domain has,
because of where it's hosted, a backup MX pointing at a large
organisation's front-of-house mailer.  If my machine is inaccessible,
the mail sits in their queue until it is.  Are they intercepting my
mail?  After all, the virus quarantine directory is no more or less
secure than than /var/spool/mqueue (OK, they run Exim, but you know what
I mean).

Taking this point further, I presume you'd hold that any ISP which
transparently proxies SMTP, so that a customer who types ``telnet
some.external.dom.ain 25'' will always end up on the ISP's mail system
is conducting interception?  This trick also allows them to log traffic
data which would not otherwise be (practically) accessible.  This
scenario I have always felt to be much iffier, so here I may be inclined
to agree with you.
