That's because the Sobig-F virus spoofs sender addresses. People who
have your email address somewhere on their Windows machine (not
necessarily in their address book, either!) and have the virus, will
unwittingly be sending our copies of the virus that claim to be from
you --and many ISPs and filter programs don't check the headers
properly.

Don't know about that, but I just received a
notice from CERT
regarding a
buffer overflow bug in sendmail, so best beware . . .
That won't affect spam, particularly. The patch has been out for a few
days, actually, and our systems were patched a while ago :-)
