Once in a while I receive spam "from my own" mail address, many

authenticated mail to be able to send mails to themselfs. Is that
possible?

Thank you for your replies, I was considering DKIM, but I was afraid of
the overhead, but I think it's worth after all. I will also take a look
to the SPF records as well.
I would like to recommend ASSP.
Apart from ASSP being perhaps the best open-source anti-spam solution
on the planet, it can block or score "spoofing" for non-authenticating
users.
It does however have a bit of learning-curve in configuring it for the
first time.
