My email account is with a local ISP, ie. not one of the majors
like gmail or hotmail. I use Thunderbird on Linux as my email
client. The ISP uses Postini for email security.
I am being flooded by spam emails, which I suspect have the
same source. All are from hotmail addresses, with the sender
name a somewhat garbled combination of letters. The "to" address
does not appear to be my own, but I receive the emails anyway.
Since neither the "from" or "to" addresses are constant, I have
been unable to filter them out in either Postini or in Thunderbird.
I'm more than a novice but less than an expert, and I think I
understand that the sender address can be spoofed, tho I'm unclear
on how my own address can be spoofed such that I receive emails
that do not appear to be addressed to me.
Certainly my basic question is how can this happen and how can
I put a stop to it. Beyond that, what I'd really appreciate is a
pointer to some article, website, etc that would help me understand
the mechanics of this type of spamming, and the methods or options
to filter it out.
