Short answer: "yes".
Long answer: *most* of the viruses out there are fairly simple
"script-kiddie" level stuff: "Open mail client. Send myself to each entry
in address book. Close mail client." However, there is at least one "in
the wild" which implements its own SMTP client: *nothing* goes through
your mail client, it just creates a load of UDP and TCP traffic. Not only
would it not show up in sent-mail, it wouldn't show up in ANYTHING except
netstat, and then only if you catch it in the act of sending!
Fortunately, implementing SMTP delivery takes several lines of code and
one or two DNS lookups, so most virus authors take the easy way out and
operate via Outlook Express ;-)
