SpamGuard works in a similar fashion to a Naive Bayesian spam filter. That
means that there are a number of factors which affect how the filter will
handle an email. Just the difference of message source can make a
difference; I have seen the identical spam message flagged as spam by
SpamGuard when it went through one Internet path, and yet not be flagged
when it went through a different Internet path.
If SpamGuard is on, and it suspects email is spam, it routes that email to
a filter labeled, "Bulk". What happens from there is entirely up to the
user. If the user configures some kind of auto deletion routing, and there
are two ways that I can think of to do that, email received by Yahoo! mail,
and tagged as suspect by SpamGuard, will never be seen by the recipient,
and no notice will be returned to the sender.

You will not get an NDR report from any mail server which has accepted
email for delivery, and placed it in a user's mailbox. What I have been
trying to explain is that Yahoo! may be delivering the email, but the user
may have some strict anti spam choices in place which will automatically
delete email without letting the user have a chance to inspect it. I have
one Yahoo! Mail account which was so heavily spammed that I configured the
strictest settings possible. I still use that Yahoo! account for the
profiles I have set up; but even I can't send email to that email account.
It gets there; but it is summarily deleted. I never see it.

Only if you can't grasp the fact that a filter may pass, or block email
when something about the Internet path is different, and suspect; or that a
Yahoo! Mail user has the option to set his filters so strict that blocked
email is never seen by the user. I have seen some pretty weird effects with
SMTP messages.
