I have received this mail, the heading "from" is blank! Is possible?
Yes, it's quite normal and is called a message with a "null return path".
Is it? I thought the return path (or envelope sender) was quite distinct
from the From: header in the message itself.
Bounce messages usually have From: headers (normally showing
[EMAIL PROTECTED]).
A blank From: header is possible, but it's unusual in normal mail from MUAs.
while the OP seems confused (he said: heading "from"), his logs show he
is talking about the envelop sender ("from=<>" of his sendmail or whatever).
