Is this to your google mail account or some other or an email address
that is redirected to your google one?

What you are referring to is called "back scatter" and it usually
doesn't remain a significant problem for long unless you are using a
catchall on your email - ie accepting anything @domain.com - in which
case you should consider getting rid of the catchall facility.

People may recommend SPF or DKIM to prevent back scatter. In theory that
is exactly what they do however the fact that very few people have
implemented any part of it and even fewer actually reject email even
where those systems indicate a fake mean that these are of limited use.

Most filtering systems will not block the kind of thing you are seeing.
It really is a matter of not accepting the back scatter and then not
worrying about it.
