Okay folks, look around you at the history of things. For more than 2 decades now, Microsoft's software products have been at the top of the list of software having security problems in CERT ( goto http://en.wikipedia.org/wiki/CERT_Coordination_Center and search for Microsoft) alerts. Viruses have, for the past two decades, routinely infected peoples computers, obtained complete lists of people email "friends", visited web sites, contents of files on your disk, trashed your disks, and otherwise wrecked havoc repeatedly.
Anyone on this list, who has participated in mail to and from this list, would provide such viruses access to email addresses which are supposed to be "restricted" to this list's members. There is no such thing as "security" when Microsoft's software is involved, and as soon as you are on a network, security becomes even more difficult to achieve.
"Guessing" that it might be an inside job is a little bit silly when there are countless ways that people on this list have exposed the list members by their use of insecure software systems and the downloading of virus laden content from the internet.
Accounts are being hacked, but as Phil notes, the "From:" headers of an email message tell you all you need to know to understand where it "did not" originate from. The last secure SMTP sever will have recorded in a "From:" header, the location the "last" insecure server to have been involved in transmitting an email message.
Look over how the SMTP protocol works. Authentication of "sending" email was not happening in the original design, and only recently, has that been "used" by ISPs and hosting companies interested in "not" supporting spam and other abuses of the email systems. This means that certain "open" systems or "insecure" systems, can provide a link from the world of "spam" if they can be accessed.
That's what you need to focus on to understand whether your account was compromised.
SMTP allows email to be from anyone, and to anyone, if the servers don't authenticate the origination and secure the transmission of the content. Until that happens, we will always have this kind of stuff going on…

>> I had theorized that they did this because they hadn't actually gotten into your swbell.net account, but it's possible they did it anyway so that they'd still get any replies from victims after your account had been secured or shut down. It would take a little longer to get rdwelclh at yahoo.com shut down since it's at a different service provider.
