Yes, this is common.

Spammers always use faked From: headers, and if they happen to use your email address then you will get bounces back from various people who got spammed.

There is a defence to this practice, called SPF, whereby the real holder of a domain name specifies the IP(s) from which emails purporting to come from that domain may be transmitted. Then, the recipient of any email can do an IP lookup on that domain, fetch the SPF record, and if the email came from an IP not listed it must be spam. It's a good idea but not a lot of people use it, and most of the big ISPs don't check SPF records because so few people have them set up. If this was universally adopted, it would force a spammer to register his own domain and spam from that and only that domain - more work for him and makes it easier to shut him down.
