[boost] Spamming through Boost mailing list

When I signed up to the Boost mailing lists, I used a unique email address 
(boost@<mydomain>.com), so that I could detect if it was being misused. 
Today I received the email below, which is obviously spam.  It seems likely 
that your mailing list has been compromised, so suggest that you check what 
went wrong with the Open Systems Lab at Indiana University.
