Somebody is forging your e-mail address, and using open relays to do it.

202.56.239.41 is owned by a company in India, see 
http://www.geektools.com/whois.php?query=202.56.239.41 . It seems to be 
an open relay.

http://www.geektools.com/whois.php?query=34.148.84.48 points to 
Halliburton. Do they have zombie address ranges?

Not much you can really do, other than contact the owners of the abused 
systems, and their upstreams. You cannot prevent somebody from faking 
your e-mail address. You can go after them after the occurance, but in 
this case they're probably hiding pretty well.
