Thanks.
A bit of a yes and a no.
I own Vlastina,cz and there is no account for Vicky?????

Simple Spoofing?
Or something else???

They have just guessed an address, and your host is configured to allow email sent to any address to be accepted. I could probably send an email to "IAmARussianSpammer@vlastina.cz" and it would be accepted.

I dont think it's anything more than that, they're just spoofing a return address at your domain.
