I've done this for some time. <companyname>@<mydomain>.com makes it easy to see who sold my address, easy to make a filter for that inbound address if needed.
Maybe there are security benefits? If every site has both a unique email and PW I figure automated attacks are a bit less likely. Could someone figure my clever email scheme out? Easily.
My thinking is it's like being chased by a bear when out hiking with friends. You don't have to outrun the bear, just one of your friends. I'm probably not willing to achieve perfect security, but if I can be slightly more difficult to figure out than <next person on the list> maybe that helps?
I do something similar with my passwords, where I include the name of the website in there in some manner. Definitely not very secure, but probably better than simply using the same password everywhere.
