Not necessarily. The from and to addresses in the message headers are
easily and often forged. They have no more meaning than the address you put at
the top of a formal business letter. To track down who really sent the messages
you need to analyse the received lines in the full message headers.
The simplest way of doing this is to use the free spamcop service at
http://spamcop.net/anonsignup.shtml
As well as being a favourite trick of spammers there are now a number of
viruses which also forge the from address. Hence people often get complaints
that they have sent spam or sent a virus infected mail message which they never
actually sent because the reply-to/from address was forged to be their address.
The viruses get your email address by searching the hard drive of any system
they infect - hence anyone you have sent a mail message to who gets infected
could then be hosting a machine which is sending out mail with your email
address as the forged from address. Spammers have a large number of ways of
gathering addresses which again they use both as forged from addresses and as
targets for their spam. See the greate spam experiment by Phil Bradley -

I often get spam with both the from and to addresses set to my email address
that does not mean that I have been hacked.
