Passing on an e-mail

[gr8gonzo]

Hi,
Basically, the only thing I am trying to do is change the e-mail address of an incoming e-mail and send the e-mail out again with the new From address.

I've set up Sendmail to feed incoming mail to this program, and that works fine. The program then opens up a socket to Sendmail:

HELO me
250 mydomain.com Hello localhost [127.0.0.1], pleased to meet you

MAIL FROM: new.address@domain.com
250 2.1.0 new.address@domain.com... Sender ok

RCPT TO: original.recipient@domain.com
250 2.1.5 original.recipient@domain.com... Recipient ok

DATA
354 Enter mail, end with "." on a line by itself

From original.sender@domain.com Thu Aug 2 14:15:48 2001

Subject: Testing Again

Testing again...

.
250 2.0.0 f76Fkie37346 Message accepted for delivery

RSET
250 2.0.0 Reset state

QUIT

Now, the mail is sent out. I receive it, but then I try the exact same thing again (exact same data, headers, etc... as shown above), and it says Message accepted for delivery, but it never gets sent. Why not???
