Problem with Postfix+squirrelmail for sending mail

[dnizard]

Hi,

I try to install a mail server, following the tuto but when I'm trying to send an email with squirrelmail, it always comes back as bulk email.

Can you help me on that?

Thanks

Any errors in your mail log?

Hi,

I was talking about this tuto : http://www.howtoforge.com/virtual-us...l-debian-lenny

But in fact, I finally successed in sendint email from the webmail.
However, I still got problem when I try to use an email client (such as outlook). I got this answer :
Relay access denied

Can you help me on this?

Many thanks

Please enable "Server requires authentication" in your email client.

That's allready done but still I've got this problem

Is there anything else I need to check?
