Oops, sorry, I misread your question.
No, if someone else installed Gossamer Mail and set it up using your domain name, it would have no effect on your installation.
The reason is that you control the DNS records for your own domain, so only you can tell where the mail will actually be delivered. As long as you say the mail should go to your machine, they can't "hijack" your account.
Cheers,
