/var/log/maillog. Also examine the headers of the forged mails, and look
for headers like sender / x-sender (in pine / mutt), x-apparently-from etc.
If the forger is logged into your server and is using pine to send the
mails, you'll also see something like
received from: forger@localhost by krec.ernet.in for <[EMAIL PROTECTED]>
etc.
Post headers and the relevant part of the maillog. Also examine your login
records (/var/log/secure) and check who was logged in at that time.
