    Receiving spam that is spoofed as being from you is quite common. They didn't authenticate as your user according to the logs you posted, so there's nothing to worry about there.

    Search the forums (and the internet) for the word 'backscatter', you'll find some details on how to improve the anti-spam system against backscatter.
