The emails in question had only one address each. I see from Yahoo's

also see that Yahoo stamps it about 90 minutes later than my ISP.

I see from your IP address that you are a Level 3 dialup subscriber.

Most likely, that has a lot to do with it. Level 3 is notorious for
being a spam-supporting ISP; it's so dirty that anti-spam services like
Spamcop won't even communicate with them any more.

Yahoo timestamps the emails 90 minutes after you send them because Yahoo
has graylisted the Level 3 mail servers. That means it refuses to accept
email from the Level 3 servers for a certain period of time after the
delivery attempt. The idea behind graylisting is that most spam is
routed through "zombies"--Windows computers infected by viruses and
under the control of the virus writers--and zombie spam relays typically
will not attempt to send a message again if it has been refused.

I suspect your emails are ending up in Yahoo's spam folder because of
your choice of ISP, ufortunately. The attachment icon may be because you
have told Mail.app to use HTML or rich text rather than plain text.
