SMTP Authentication and Email Headers question

[Claude Almer]

Hi there,

Could you please explain what stops yourdomain.com using calmer.com's SMTP to send out mass-emails (or, for that matter, a single one).[nbsp][nbsp]I'm used to password authentication or, pop-first, which amounts to the same thing.

Also, when I send emails via FQ SMTP, on email header says:

> Received: from unknown (HELO calmer.com) (144.132.191.201) by calmer.com with SMTP; 21 Jan 2001 00:23:19 -0000

Where the helo calmer.com is what I specify to identify self to SMTP Server.

How can I get rid of the "Received: from unknown", since I specifically specify calmer.com.[nbsp][nbsp]Same happens if I change that into say "Electronic Post Office", this results in

> Received: from unknown (HELO Electronic?Post?Office)

Cheers, Claude.

I'm glad someone else brought this up. It has been on my mind, too.

I'd decided, that the reason that there is no authentication, is because our scripts need to be able to use the SMTP server.

Would FQ probably block IP addresses that tried to abuse our server?
